No-compromise fuzz, featuring clean boost, overdrive, and distortion.

The Fulltone CT-1 Catalyst Guitar Pedal is equipped with a simple circuit that uses only discrete FET's to achieve its throaty roar. But the Catalyst stompbox brings something more to the table because it to does things that many other fuzz pedals can't.

With its mini-toggle switch set to "Spark," the Catalyst effect pedal offers clean boosts, sweeter overdrives and all sorts of distortion sounds. Want more? Flip the switch to "Flame" and you'll be treated to a host of less civil overdrives, unique distortion voicings, and a plethora of vicious Fuzz sounds, all of which clean up with a twist of your guitar's volume knob, with a linear transition from clean to mean.

To further enhance your tonal control, the Catalyst guitar pedal offers a pair of very effective low-loss tone controls that set it apart from the masses. Standard tone stacks often end up cutting so much gain that the effect designer has to make up for this loss later in the circuit, and many times you loose some of the magic in the process. Not so here because the Fulltone CT-1 Catalyst pedal's low-loss Bass/Mids knob dials out the flubby low-end, with the added bonus of supplying varying amounts of rich midrange when the Bass/Mids knob passes the 3 o'clock mark.

This midrange, on top of an already wildly distorted tone, has the effect of increasing sustain to insane proportions as well as breaking you out of the standard super bright/super bassy Fuzz mold. Need to smooth out the highs? Simply turn down the Treble mini-knob-a low-loss hi-end roll-off-allowing you to shave off as much of the treble as necessary.

Finally, many Fuzz pedals can have wacky input and output impedances, making it difficult to match-up successfully with wah-wah pedals and non-true-bypass buffered pedals. The Fulltone CT-1 Catalyst has none of these issues, sporting a friendly 1-meg input impedance and an astonishingly low 10K output impedance. When's the last time you had a fuzz work with a vibe or wah-wah? Things have changed, indeed.

  • True Bypass switching
  • Volume Knob
  • Gain Knob
  • Spark/Flame toggle switch

Take your six-string from clean to mean with a twist of a knob. Order your Catalyst pedal for a killer price.

A very different dist/fuzz/overdrive/boost pedal

By Alan the Guitar Geek

from Salt Lake City, UT

See all my reviews

Comments about Fulltone CT-1 Catalyst Guitar Effects Pedal:

I went to Guitar center interested in the FullBoost, OCD, or PlimSoul. I tried them all out, but this was the one I took home.I have a fender Pro-Reverb (2001ish) w/ a drive channel, and a Blackstar HT-Dual. So I already have some good standard OD/Dist. I was looking for something different.I tried out the Catalyst because it was plugged into the same chain as the PlimSoul.What really hit me was how responsive and sensitive this pedal is. In "Spark" mode it's still pretty transparent and clean when you play lightly, even with the gain turned up. But when I play hard, it gets a nice burst of drive. It reminds me of the natural drive sounds on early Paul McCartny/Wings records.It's definitely a fuzz pedal (a nice contrast to the Marshall sound of the Blackstar). But it's not a cheap sounding fuzz.This is great for classic rock. I still have a lot to learn about this pedal, but I haven't been as excited about a pedal in a while. I can't say it's THE only drive pedal you'll need. But it's a fun interesting addition.I play a 1980 Gibson solidbody 335 Firebrand. I tried this through a solidstate fender at the store. I didn't like it as much through my LabSeries L5, but I LOVED it through my Fender Pro-Reverb.

Incredible tone from clean to fuzz

By Anonymous

from Undisclosed

Comments about Fulltone CT-1 Catalyst Guitar Effects Pedal:

This pedal really does do it all. If I could only have one pedal in my arsenal, it would be the Fulltone Catalyst. You can dial in so many different sounds with this thing. The fuzz is more classic sound, but you can definitely dial in that Black Keys type fuzz as well. Will the clean really sound Fender clean? no, but if you want that get a Fender amp a play clean. But the overdrive, distortion, and fuzz tones are amazing. I will say that this pedal is low impedance, and when turned on will very noticeably lower your overall volume. This is not a problem if you're using it throughout the entire song, just turn up the amp. But if clicking on and off during a song, I recommend getting a Fulltone fat boost and putting it after the catalyst in your chain. This is handbuilt and wired, and it's obvious from the sound. The distortion and fuzz have a lot of character. It's a different fuzz tone than a big muff of zvex which to me are strange sounding fuzzes. They sound like whales communicating under water. The only other fuzz I've played that stacks up to this is the Keeley Fuzz Head, but the Catalyst is much more versatile. The pedal is very interactive with your guitar volume. Guitar volume needs to be on 8 or 10 for full character. Back guitar volume to 5 and it cleans up nicely. I like to leave this and my fat boost on for the whole song and just adjust my guitar volume when I need to clean up. I have played this with a Les Paul through a Vox AC30, and suprisingly it did not sound muddy. The single coil guitars really shine through I must say. Awesome pedal! You won't be sorry.

Didn't hit the mark it sets...

Comments about Fulltone CT-1 Catalyst Guitar Effects Pedal:

What do you really get with the Catalyst? This pedal is meant to be a lot of things. It's supposed to cover the spectrum from Clean boost to Overdrive to Distortion to Fuzz. Really? Does that sound to good to be true? It is. Yes, those sounds are in the pedal, but within a very small and hardly tweakable range. Most of the spark mode is a clean boost. There is a small fraction between 3 o'clock - 5:30 that it has some really nice saturation. Flame mode has a bit more versatility. And overall produces a nice Fuzz tone that you can articulate with. The EQ is very useable. The 2 things this pedal does well is a clean boost and unique fuzz tone. There isn't much room inbetween for the other sounds. It WILL NOT be a replacement for a good dedicated overdrive pedal. I've plugged this in several times, really taken time to tweak the knobs and play with it. Honestly I'm not real impressed. Which is a bummer because I have 4 or 5 other Fulltone pedals and all have been absolutely over the top fantastic. This one falls extremely short of the expectations it sets. Even with the fuzz range, it does a vintage sounding, kinda thin fuzz tone well that has unique character. But you're not going to get warm rich thick fuzz like you do with a Big Muff Pi. It is not as versatile as they make it sound. I'm affraid my first impression of this pedal from demo's I'd heard was correct. It just doesn't make the grade.

    Comments about Fulltone CT-1 Catalyst Guitar Effects Pedal:

    THis pedal is SOOOO versatile that (by reading some prior reviews) a lot of folks can't decide what to do with it. This IS a 'fuzz', a top-shelf 'clean boost', and a 2-mode OD....just not all at the same time (duh!). In other words, it's 3 effects in one, but you *will* have to choose which you're using at any time. That's why 'all the fuzz' is in the last quarter-turn of 'Gain' in both modes. The trim-pots give all the color you want once you're up in the fuzz or distorto-tone range. The OD part of the Gain-sweep has the most range, and you can go way past any TS-8/9 sounds with the 'bass/mid' knob. The EQ-able Clean Boost is what it is (Gain at 0, volume and EQ-pots to taste)....I'm not putting this on my pedalboard (which has all 'dedicated' pedals for specific sounds). I *am* taking it with a guitar any time I go to a 'jam', or expect to play through other peoples' gear: this pedal, one way or another, will embellish and/or fix any rig you find yourself playing through.
    This Fulltone CT-1 is the Swiss Army Knife of pedals!

    Great Fuzz and Clean Boost

    By Jeb-Goe-e

    from South Carolina

    Comments about Fulltone CT-1 Catalyst Guitar Effects Pedal:

    Great pedal for both a fuzz and clean boost. I purchased mine a few months ago and its wonderful. Like many fuzzes, there is no eq or true bypass. Major tone suck and I just can't have that. Fulltone knows what they're doing. The eq has a wide range of possibly, not just tonely by itself but also shaping the fuzz to match the pickup your using. The clean boost can be used as a db+ boost or keep it on to add a little addition shimmer to the sound. Thanks Fulltone!

    Comments about Fulltone CT-1 Catalyst Guitar Effects Pedal:

    This offers nothing over the OCD. it goes from clean to fuzz in a fraction-of-a-turn of the knob. It's tone is nothing to write home about. Save your cash, this is a fancy paint job and qulaity parts around a lousy circuit design (or execution). I just don't get it. I vae 2 OCDs- they are great. Clyde wah- great, Deja-vibe- great. Catalyst? No thanks...

    A Dream Come true

    Comments about Fulltone CT-1 Catalyst Guitar Effects Pedal:

    I gotta say I am really confused as to why there are negative reviews of this gemThe CT 1 is a dream come true.I have dropped 3 pedals because of picking up this tresure.MXR Dyna compDS 1 ModBig Muff Tone Wicker All replaced by this gem. The clean boost ran on 18v w some added bass gives the same feel as the DynaW the Treble maxed and the bass dropped I get the distorion of the DS1The fuzz tones are deadly! I bought the BM wicker because you can by pass the tone knob and have more control over the fuzz. The CT 1 superceds that control. With the mid boost I can achieve the speaker crackle of the Muff and much more. Much Much more. I absolutely love this pedal.

    Great pedal

    By azreich

    from Flagstaff, AZ

    See all my reviews

    Comments about Fulltone CT-1 Catalyst Guitar Effects Pedal:

    I've played guitar since 1965 and have had virtually every pedal on the market. You can get a good overdrive sound with your amp and guitar on 10, but that's not always possible and of course, you only get one sound with some variations. I bought the Catalyst thinking it was just one more pedal that would end up in box of pedals, but I thought I'd give Fulltone a chance. Well,,,,,,it made my other pedals OBSOLETE!!! The sounds I can get from this are awesome--virtually every distortion/overdrive sound I like. I play six guitars, but mainly a '68 335. I use a Lab Series 9 and a Lone Star 100 watt with 4-10 and 2-12 cabs. I'm going to buy an OCD pedal as another play toy to see what new sounds I can get.

    I thought Fulltone was better!!!

    from Midlothian,IL

    Comments about Fulltone CT-1 Catalyst Guitar Effects Pedal:

    I recently bought this pedal after hearing some demos and reading reviews about it. I thought that this would be a great pedal to handle a wide array of tones. When I received the pedal it was constructed very well. Knobs turned smoothly, nice paint, etc. When I plugged this in using a strat and a tele I started to use a few of the Fulltone suggested setings. The bluesy neck pickup setting was OK and this pedal works pretty well for a clean boost but after messing with the other settings it just got worse. In the manual that comes with this it states from Mike Fuller that you get a clean boost to OD to distortion to crazy fuzz with harmonics and near endless sustain. Other than the boost I found none of the other qualities mentioned. This thing sounded like a cheap transistor radio on the fuzz setting reminiscent of the Dunlop fuzz but crappier. I was running through a Fender amp with only guitar and cable. No OD!! No creamy distortion!! No magical fuzz tones!! After 30 minutes of playing, the 9V jack started making noise and was cutting in and out. I guess I have a different understanding of what boutique is than others but for now I will stick with my Keeley SD-1. Garbage pedal and it's being sent back. I am sure Fulltone makes other great products but for my first Fulltone pedal I was disappointed and the pedal was completely unusable.
