OVERVIEW

No menus, no screens, just plug in and play with four mindbendingly great effects!

With classic guitar tone disappearing down the road of digital modeling amps and effects, Carl Martin is proud to introduce the Quattro  four of the most popular Carl Martin effects in one package.

The Quattro begins with Carl Martin's award winning Compressor/Limiter circuit with single controls for compression and level. The Two-Channel Overdrive has switches for on-off and for selecting between the crunch and high-gain stages, and controls for tone and level. In classic fashion, the Vintage Chorus has a speed and a depth control. Finally, the vintage style Echo has controls for level, tone, repeat and tap-tempo, as well as an on-off switch. No hard to read screens, no menus to scroll through, just set-up and play. There is no simpler multi-effect pedals on the market! There is also an effects loop built in between the overdrive and chorus effects for that special drive or fuzz pedal that is part of your sound.

You also get famous Carl Martin build quality, ultra quiet switching, a high quality on-board regulated +/-12V power supply which allows use of the finest components allowing the greatest amount of headroom, and low output impedance which leaves your amp sounding exactly like your amp.

I have owned and played a ton of guitar processors, use a Boss GT-Pro and live miking in thestudio, had every stupid tone robbing effect and gadget and finally see the light. This is simple, sounds amazing and as I said before... if you need more than these effects to play then you are just hiding behind a bunch of junk noise.
What I liked about it was the lack of features. Been playing a long time and the more years pass the less I want to F-around with layer upon layer of menus that will work in the studio and then blow when you play live. The transition from headphones to monitors to a club's monitors and your amp, never works. So, this thing you plop in front of you and... boom, your ready to go. Two overdrive settings, real-world chorus, great analog delay, and a compressor that is plainly the best I have used in 42 years of playing. If you think you need anything else, you will be playing in your bedroom on YouTube for the rest of your life. Unless of course you play in a Flock Of Seagulls tribute band.
Built like a tank, I am sure it will take a beating. I read another review that the said the knobs turn too easy.... they don't, mine was dampened fine. The only thing I am curious about is the AC cable... hardwired and no ground. I am sure they have a reason for this and the unit runs silent so that wasn't an issue. Also, I would recommend contacting the support dept of any company before you buy their products. I emailed Carl Martin a question before I received the item and they responded the same day... AND... it was the CEO.
It seems a little pricey but if you add up the Carl Martin effects it would take to make this pedal I calculated about 1400.00 So, it's a deal. No plugging in 4 - 5 boxes and running tone-sucking patch cables between them.

I may have recieved a defective unit. The effects sounded great, but produced a really bad hiss (though mulitple amps, power sources). The chorus was worse of all (much lounder hiss than the other effects). I really wanted to like this, but had to return it.
Nice features, but everything was really noisy. The whole unit hissed really loudly when I hooked it up to my amp (much worse than the 2-3 BOSS pedals I have). The Chorus was the most noisy of the effects - I ended up returning it...
Seemed well built, but very noisy. I was not going to spend this much only to have to add a noise gate. I may have received a defective unit as other reviews I've read were great.
Expensive! I had high hopes for it and was willing to pay the price. Noisy! I am going back to the individual pedals that work for me.

Comments about Carl Martin Quattro Analog Multi-Effect Pedal:

Do you want one high quality multi effects pedal you can use for your stage rig?

I wanted an all analog signal path, since I have a pretty sweet sounding hand-built amp, and you know how digital effects pedals can destroy your sound.

Compressor: I play mostly country music with a Telecaster, so the compressor is an integral part of the sound. I kind of wish I had a bit more control over the compressor, such as an attack, and perhaps blend control. This compressor can really squeeze your sound - a little goes a long way. I set mine at only 9 O'Clock and still get a very squashed sound. I set the volume to make the output a bit higher than the input to push the front end of my amp a bit.

Overdrive/Distortion: such a nice overdrive with my amp. There are two drive knobs - a low gain and high gain - with a switch for selecting which one is active. This is a great set up, since you can use Drive 1 for nice, barely overdriven rhythms and Drive 2 for high gain leads. Note that there is practically no increase in volume with switching to Drive 2 if the Drive knobs are set about the same, so it's very smooth switching back and forth.

Chorus: I don't use chorus, but you may like how subtle the effect can be, just adding some fullness. A very good chorus, but not designed for radical modulation effects.

Delay: Love the delay. It has tap tempo and that's the only way to set the delay time, so remember to tap in the initial value. Very analog-sounding, and the tone control is very useful, allowing the delay effect to stay in the background and not interfere with lead playing at all.

This pedal is also nice and quiet, at least in my rig. There is a line buffer that cannot be bypassed, but it's a high quality buffer, I believe much better than the average Boss pedal. When you think of its intended purpose as a quick, all-in-one pedal, it makes sense that it would have an always-on buffer.

The power supply is built in, so you just plug in the two-prong AC plug to your power bar. No wal-wart here.

The only things I would change is to have a blend control (blend dry and compress signal), and an attack control, and perhaps a delay time control. However, these extra controls would take up more space, and comprimise the minimilist design of the unit, so perhaps it's perfect as is.

Comments about Carl Martin Quattro Analog Multi-Effect Pedal:

This is an excellent choice for a one piece unit to cover all the basics. But, don't take my word for, check uout Pete Thorn's demo on youtube. He uses it for fly dates where he never knows what amp he'll have available. I use to own an earlie model w/ tremolo instead of chorus and I miss it and will buty the new Quattro a.s.a.p.

Awesomeness!!!

By Anonymous

from Undisclosed

Comments about Carl Martin Quattro Analog Multi-Effect Pedal:

I have owned this unit for about six months now and am thoroughly satisfied. I am running stereo out of the Quattro into a Bogner Alchemist 2x12 (super-awesome) and a Marshall JVM 410H with THD extension cabinets (good, but should have gone with Marshall cab with Celestions...anyway...). This rig is outstanding, albeit a little bulky to move about, but well worth the setup time, the tone with the Carl Martin is incredible. I love the Tape Echo and Distortion stages on this gear, they are really great. The compressor is fat and provides real punch; and the chorusing is perfectly textured. Overall, happy that I bought it; would buy again in a heartbeat! If you don't have it, and you dig Analog gear, get it.

LOOKING FOR THE PERFECT TONE!

By CLASSICPLAYER

from cd. juarez, MEXICO

See all my reviews

Comments about Carl Martin Quattro Analog Multi-Effect Pedal:

If you're looking for the real tone please read this, if you play punk or metal or non sense music styles please look else!This is an absolutly beautyful multieffects, Yes It, doesn't have all the features like others multi like boss, digitech, tc electronics,line 6, etc,etc, but who cares! This multi is in another class, you can't compare it, and for the price i really think is not so expensive.You don't have any digital tweaking here like lcd boards, no parameters to program, If you're searching for extreme sounds and weird tweakings, forgett it, it's not gonna happen!If you looking for serious and pro sounds in the rock, blues, pop, jazz, indy etc, etc, this is your choice! You have COMPRESSOR: a very sweet compressor studio like sound only 2 knobs output and compress, you can use it for booster too!,OVERDRIVES: The first one is in the plexi mode warm and sweet, you cand find amazing tones here from ENGLAND to USA. The second one is more agressive yet warm and musical, I don't use it very much, but with a good tweaking in your amp equalization you gonna find ver hard tones to riff, one thing I like is what no matter how much drive you put in one of the 2 drives section it will no affect the output signal, that's very useful in a live situation!Then is VINTAGE CHORUS: this version of the cuattro comes with this effect instead the tremolo effect in the previous version, (you're gonna really miss the tremolo. What you have here is a very warm and musical chorus even if you want to abuse of this effect, it won't let you because all the parameters are very balanced, so you have a colorful chorus here in the way of the RED WITCH EMPRESS CHORUS, very analog without the weird ranges of the rate and depht! if you like that old POLICE, THE SMITHS, OCEAN BLUE and all the good NEW WAVE of the 80's, this is your choice!Finally we have VINTAGE ECHO: wish is just an analog sounding delay, like the old tape echos, like i'd said before look else where if you want dramatic and digital sounding delay. what you have is a delay level knob, a feedback knob, and tone knob from dark to bright sound, and a tap tempo footswitch to control the speed of the delay, this is very useful in a live situation and for recording!I like this effect very much is very musical and you can do very good stuffs here a la THE EDGE, with a good imagination and well playing. One thing i really like is the fact that this delay really sounds like the old analog ones, it has that sweet distortion on the delay repeats, don't be afraid of this, just a little amount of low fi signal makes a better sounding music in this digital music world today!, So If you want really cool and fine effects and you don't need more than the essential, please buy this!

Sweet, Sweet, Sweet

Comments about Carl Martin Quattro Analog Multi-Effect Pedal:

With all of the modeling pedalboards, Line 6 amps, pods, and stompboxes out there that are good for quick, cold approximations of tones, this unit combines an intelligent combination of four integral guitar effects that are analog, warm and expressive. The workmanship is excellent, made in Denmark, with great signal strength and no noticeable noise or degradation. The controls and layout are incredibly simple, sans the exhaustive menus and LCDs of today's modern equipment. Most importantly, the sound quality and tones are full, rich, layered and real. No digital harshness here. It Plays excellent jazz and blues through both solid and hollow body electrics. (I used a Les Paul, ES-347 semi-hollow body, and telecaster and all sound fantastic. This unit is a must have and will be the platform for your rig. Carl Martin hit a home run with this one.

Best I've tried yet!

By JJ

from FL

See all my reviews

Comments about Carl Martin Quattro Analog Multi-Effect Pedal:

I've only had this for a bit but can't see myself ever getting any other kind of pedal (and I'm ALWAYS buying new things). I added a Fulltone Clyde Deluxe wah in front of the signal and they cooperate very well too. May try a TS808 in the effects loop one day, but the overdrive channels are actually pretty nice sounding with the gain controls at the 8-9 o'clock position (very mild grit and kick in OD2 if I want more). The compressor sounds really good and the chorus and echo both function perfect too and introduce VERY little noise to the signal.
Not much in the way of features, but that's exactly what I wanted....simple, easy, and straightforward.
Sounds coming out of this pedal are awesome! Clean, non-evasive to your tone, and easy to tweak (even with your toes if needed).
Like others have said, add up these effects/cables/power supplies and you get a great bargin with sounds that are fantastic.

Simply awesome..literally

Comments about Carl Martin Quattro Analog Multi-Effect Pedal:

This has been a great substitution, not addition. I was running a Tonebone Plexi dual, an EH chorus, an analog delay. I've replaced them and the pedalboard with this. If you're a "triple rectumfrier" full out shred head, this wont work. If you like a gritty OD, excellent chorus, crisp boost from the compressor to jump leads over the din and switch as you go delay, this is great. Instead of a pedal board, I just plug in this baby and I'm ready to go. Les Paul to pedal to Fender 63 reverb unit to my amp which is a 67 Bassman 50 with solid pine cabs with vintage 30's and greenbacks. Simple. Straightforward. Easy. Sweet. Can't say enough about it.

Comments about Carl Martin Quattro Analog Multi-Effect Pedal:

I have had this board for over a year and must say compared to Digitech, Roland, Line 6 and the other major digital modeling multi-effects processors, this is the simplest, most user friendly, and best sounding board out there for a relatively bargain price. Everything is integrated and the sound quality is warm and expressive. No noise, harsh digital coldness of tone or that frustrating time lag latency between playing, signal processing and sound. If you like warm, true, expansive analog tone from jazz, to blues to rock this board is priceless and a must have. Also simple, rigorous and well made. Buy it, you won't regret it.

    Great sound, easy to use

    Comments about Carl Martin Quattro Analog Multi-Effect Pedal:

    All Carl Martin products sound great. They consistently provide clear, reliable, noise-free performance. This beauty just happens to encase all the most musical and useful effects in one box.Want compression for a killer clean tone? ...just press that button. Need some crunch or heavy authentic distortion? Step on one of those buttons! It's that easy! Need to adjust something? Tweak the dedicated knobs in real time. It works like it is supposed to. This thing is for real players who want real tone NOW! ...no scrolling, no menus, no manual. Plug it in and rock! It is top quality and when you consider all you get, it is a bargain. Save the hassle of jumper-cables, midi foot-controllers, and countless hours of tedious manual-reading. Get all the most useful, musical effects in one box and be done. You will thank me.

    Comments about Carl Martin Quattro Analog Multi-Effect Pedal:

    Wow! This thing blew away all my other stomp boxes in terms of quality and sound.
    As soon as I hooked this up with the 4 cable method to have the chorus and delay in the loop I knew it was a winner. My tone has improved leaps and bounds.
    I think with the 12V power and not running a bunch of patch cables this unit has improved my rig overall even when I'm not using its effects.

    I have been through more effects than I can count, digital and analog. Singles boxes and multi FX units.
    This is the one if you are into great non digital tone. Well worth the $$

      Comments about Carl Martin Quattro Analog Multi-Effect Pedal:

      I thought this was my dream pedal- a multi effect unit that was analog with knobs, not digital with menus. However, after trying it out, I was very disappointed with the sound quality. The compressor is dull and lifeless, killed the tone of my guitar. Chorus is OK, nothing special. The overdrives are generic and without any distinctive character. The echo is also dull, lifeless and tone sucking. Not at all what I expected, returned it the next day.

      This box ROCKS!

      Comments about Carl Martin Quattro Analog Multi-Effect Pedal:

      Super high quality, like all Carl Martin's stuff. Tone is absolutely gorgeous. And is it so simple. Plug in your guitar, plug the unit into an amp. Do yourself a favor, plug into two amps for a stereo eargasm. This is a real musical instrument, not a digital toy. The built-in high-voltage power supply insures high-headroom and low-noise. You won't need the manual. Get it. You will spend more time playing and less time tweaking.

      Comments about Carl Martin Quattro Analog Multi-Effect Pedal:

      All CM products are great. This thing just combines the most sought-after effects in one super-easy-to-use box. The distortion is fantastic and "feels" just like my old tube amps. The compressor is one of the best in the world for guitar. Retro delay sounds like early Zep recordings, only doesn't require tape loops. Tap tempo is a nice addition too. The chorus is lush, authentic and rich. You'd spend a lot more to get this stuff separately, and in this format, it is so easy to use. Plug it in and play. You will be delighted.

      With all the "Digital" Multi effects pedals out there I'll take this analog one every time. No useless sounds, no programming, just good easy to use sound. It's not a "Metal Machine" but for just about everything else this is the pedal. I love the way I can get a nice blues sound with my strat, with 1st overdrive. The second one is nice for most rock songs. I highly recommend this pedal!

I add an EP booster after it in the chain and can easily play rock/country shows with no problem. It's quiet,the drives & compressor are great. The chorus is subtle but works great and the delay sounds good too. It also sounds good regardless of what amp I plug into as well.

          I was looking for a multi-effect device that would enable me to route the time based effects to the loop in my amp and drive effects to the front end...I decided on the Quattro(which was an open box but came in brand new condition) ,partly because of that capability and also because of its built in power supply..After an initial concern ,I think I made the right choice ..I hooked it up using the 4 cable method and was a little worried because It turned out that it really didn't sound right that way...there was a noticeable loud popping sound when I hit the chorus switch and it cut out the on -board reverb on my amp..Sigh..I looked at it for a while thinking I was going to pack it back up and return it..then for the hell of it I plugged it straight into the front of the amp and that's when the magic began...It loves my Fargen Blackbird V-2 combo as much as I do!..so now I can use the loop on the Quattro for additional effects...there is not a bad sound that comes out of this thing..and It simplified the wiring scheme on my board...I can only think of one addition to this that would make it absolutely perfect...a 9v power supply tap for my other pedals...hey a guy can dream can't he?..Very durable and well laid out...nice job Carl Martin
