When it comes to gear, stompboxes included, sometimes simpler is better. It doesn't get much simpler than the LPB-1. Yet, even with just one knob, this pedal is extremely versatile. If you need a clean boost for solos or parts that need to cut through the mix, this little box will do it. You can also use it to overdrive a tube amp to create a meaty, saturated tone that is more responsive and natural sounding than using a distortion pedal. Or, use it after a good sounding overdrive pedal for added depth, harmonic texture and sustain. My favorite use for this pedal is to set the LPB-1's volume at around 1- 2 O'Clock and kick it on over an already moderately overdriven tube amp (like, for example, my Marshall JMP 50). That way I can go from a nice grindy rhythm tone to a fat, throaty lead tone for solos.

Compared to the equally awesome MXR Micro Amp, I hear more of a midrange emphasis when the LPB-1 is engaged. Even at cleaner settings, there is some added midrange coloration there that fattens up the tone a bit. I happen to dig it. However, if you are looking for something a bit more neutral sounding, you might want to go with the MXR or another brand. One non tone-related advantage the Micro Amp has over the LPB-1 is that its metal case is much heavier and, therefore, is less likely to move around on stage. Obviously, this is a non-issue if you have one securely attached to your pedalboard.

Finally, I had a hard time believing that a pedal priced this low (and made in the USA, no less) could actually be true-bypass. However, once I took off the bottom plate and saw the 3PDT foot switch inside, I was happily able to confirm it is! Every guitarist should own one of these little gems!

Needed a simple clean boost that didn't color my sound, and it works well for that. Very well built - I don't think I could break it if I tried. That said, I'm about to get rid of it. The volume knob gets 10X louder if I move it just a hair past where I set it (usually 9 o'clock). Considering it's close proximity to the switch, it's likely to get a nudge. I've had way too many surprises on stage because of that. Also, if you place this after your distortion pedals you will find that the amount of boost varies greatly depending on what comes before it. Some will say that it should be placed before distortion, but highly compressed distortion pedals will cancel out a boost that comes before it. Sounds great, built well, but too unpredictable for me.

    This is a must have for those who love the tone of their amp but just need more volume and sustain to cut through the mix.
    I LOVE this pedal! If you use a small wattage tube amp and need a boost for leads without losing tone like most distortion pedals do this is for you. Killer sustain!!!
    Nice small package looks pretty tough, all metal.

    A Great Ballsy Pedal

    By Cuzzman

    from Rhode Island

    Ask me a question

    Comments about Electro-Harmonix Nano LPB-1 Power Booster Guitar Effects Pedal:

    The only reason I did not give it a 10 rating is because the foot switch is located a bit too close to the power adjustment dial and your foot may have the tendencey to hit it and turn it when stepping on the foot switch. It takes a bit of getting used to.
    This pedal is the ultimate is power booast pedals! Its a ballsy pedal! Even setting the turn dial at about 1 or 2 gives me the added extra boost I need to be just above the rest for my solos to cut through.
    Perhaps the best feature is that is provides a natural-sounding boost without changing the tone. Other power boosters often alter the tone when activated, they not only boost the volume but they also boost the bass and/or treble -- But the Nano LPB-1 Power Booster is a natural!
    I highly recmmed it to those looking for a great power booster. You'll probably want to pick up the 9-volt adapter for it as well to eliminate those battery chnge nuisances.
    Its sturdy and well consructed.
    At the price its more than well woth the money!

    Comments about Electro-Harmonix Nano LPB-1 Power Booster Guitar Effects Pedal:

    I bought this pedal wanting a clean boost that wouldn't color the sound and this pedal is exactly what I needed. I use it mainly for solos for a little extra clean kick. It drives my Bassman into tube saturation heaven! Put this pedal in your signal chain after an overdrive or distortion pedal and enjoy the supercrunch. It really makes my tubescreamer sing. If you're looking for a power booster that is really clean and does the job well, this is the one for you. There are certainly more expensive ones out there but I've compared this one to three others (a piggy one, a killy one and an m_r) and I like the sound of this one best. Plus it was the least expensive one of the lot! BUY IT!
    Has true bypass. Simple one knob operation.
    Sturdy metal case and good solid switch. Input and output jacks are top notch.
    You CANNOT beat the bang for buck on this item. Its not cheaply made at all!

      its a cheap pedal and i suppose you get what you pay for. I had purchased this pedal at sam ash on my way to a gig for a quick cheap boost and probably the worst mistake ive ever made. If you put it through a chain of distortion it muffles out the distortion adds bass, and over all just changes your tone. Save up and get something better.

      Ask me a question

      Comments about Electro-Harmonix Nano LPB-1 Power Booster Guitar Effects Pedal:

      I feel it can beef up the sounds of most amps! It can also help boost the sound if other effects begin to kill the volume.
      The first EH guitar effect I purchased was a Muff Fuzz. This was back in the 70s and it sounded great through both a Pignose and an old Crown amp! This LPB-1 also sounds great through my Vibro Champ and NOS Blues Junior. It really wakes up the amps in a positive way. Just on its own it improves the tone. I need to start trying out other effects with it and hear the results. I can now record at lower volumes and still get an excellent tone with this device!
      I'm very impressed by it
      I definitely would get another if I lost this one.

      Comments about Electro-Harmonix Nano LPB-1 Power Booster Guitar Effects Pedal:

      Great pedal, invaluable to me. It colors the sound a tiny bit, a bit of bass and lower mids but a great volume boost. Adds a lot of gain with an overdriven or distorted amp.

      I use it for certain solos or for certain rhythmic parts. Really adds some grit, I also use it to help manipulate feedback.
      Simple, one knob, one button, 9v.
      Metal (assuming aluminum) case, sturdy button! Think is built solid.
      For me, it's a little stingy with the price, but I'm happy with what I paid for,

      Comments about Electro-Harmonix Nano LPB-1 Power Booster Guitar Effects Pedal:

      I purchased this product a couple of years back to increase my soloing volume to help cut through the mix of my band. It did this very well but it also added a little distortion while doing so. I was running this through the front of my amp ( Marshall TSL 100) and causing it to break up prematurely. After a lot of different combinations on my pedalboard I finally achieved what I had been after. I split the signal on my effects and sent the overdrive and the distortion into the front of the amp and LPB-1 with my time based effects through the effects loop. Wow!!! I keep the LPB-1 on at all times set at a lower volume (about 10 o'clock). This fattened and tightened up everything on my amps without any effects. The result is a full rich sound on any channel. Now I use my overdrive pedal as a boost and have learned how to properly use the volume control on my guitars. My time based effects line is made up of 1) Noise suppressor, 2) Tremolo, 3) Phaser, 4) Vibrato, 5) Flanger, 6) LPB-1, 7) Lexicon MX 200 for delay and reverb. My distortion, overdrive, compressor and wah go to the front of the amp. I also play this setup on a Fender Hot Rod Deluxe for the smaller venues and and it is just as impressive. My amps have come alive my tone is phenomenal. The best money I have ever spent. No problem cutting through the mix! Be patient, experiment and find the combination that works for you. Great pedal

        Comments about Electro-Harmonix Nano LPB-1 Power Booster Guitar Effects Pedal:

        This pedal boosts the signal of your guitar, so that you can hit your preamp tubes harder, and get a nice tube saturation at a more reasonable volume. It also gives a nice little bass bost without otherwise changing your tone. If you have a solid state amp, you can still use it as a volume boost, but this was designed to push a tube amp. I use my amp at half power, and keep the LPB-1 on all the time for a crunchy rhythm tone. It's simple pedal that does what it was designed to do.

            Comments about Electro-Harmonix Nano LPB-1 Power Booster Guitar Effects Pedal:

            I can't recommend this pedal due to the fact that the LED indicator status light quit working after I got it installed on my pedal board. I'd return it but Musician's Friend's policy says they won't accept returns if the item isn't in new unused condition. Unfortunately for me I already removed the rubber feet and glued velcro to the bottom. It's pretty lame that Electro Harmonix can't make a pedal that will last more than a couple of hours. I'll never buy any of their products again. I gave it 2 stars because the boost function still works. No telling how long though. Shipping to have it fixed will cost almost as much as the pedal. Guess I got stuck with a lemon.

              I purchased this for use with a Fender Super Six I use with my Americana band...adds a great bit of grit without having to crank up the volume.
              Decided to try it on my solid state amp (for my Rock band) add thickness and a great way to add boost for soloing (when used through the FX loop)
              Wont add much boost through a solid state when ran direct.

                This pedal does boost the sound, but it adds distortion as well. It's fine with electric guitars or other instruments which have an electric character to their sound initially. However, If you boost an acoustic guitar, vocals or something where you want a clean signal, you will be disappointed because the higher the signal is boosted, the more distortion will be evident.

Me and my buddy chill and write music and when there is a nice little fancy walk or sweep i wanna do, ill click it on off and it is a very sastifying few seconds. Or if you wanna push it, use it for a bass solo. Or what its meant for. Lead guitar. This thing, if used at a tasteful rate, it is boss for guitar or bass. This is a must have for anyone who is sick of your little fill not getting recognized by your friends.

                This box does one thing and does it well. It makes your signal louder and it doesn't mess with your tone. I like it because it will give you any volume level from zero to "Oww! My ears!" It's solidly constructed and doesn't take up much space. I use mine after my overdrive and effects for a solo boost, or to make up the difference between humbucking and coil-tapped modes on my guitar. No bells, no whistles, just a simple well-made one trick pony. It's cheaper than the other booster I used (the Seymour Duncan one) and I like it better-- even on minimum volume the Duncan was more boost than I wanted. On the whole, I like it and would buy it again.

                Comments about Electro-Harmonix Nano LPB-1 Power Booster Guitar Effects Pedal:

                I got this pedal after a buddy at a guitar shop recommended it. The LPB-1 was one of the first preamp booster pedals to come out back in the '60s, and the sound shows. I now use this as my main overdrive pedal with the knob at about 10 o'clock. This pedal is perfect for overdriving tube amps and really getting that classic rock sound, from a little bit of grit to screaming, scratchy distortion. The pedal does a good job of letting you still be in control of your tone (albeit it does brighten the sound, but most boosters do). Also, I've found that if you put a simple smooth distortion pedal in front of the LPB to create a great fuzz-like tone. All in all, all tube amp owners should get this pedal.

                i decided to give this pedal a try because i found it for cheap, and i'll pretty much try anything if i can find it cheap. and, i love it!!! i have it running to my vox ac15c1 and it just makes it scream. would i use it for a rythm tone? no. it gives my tone a lot of brightness, and it's not warm enough to play decent sounding chords. but that's NOT the pedals fault. it's because i'm running through a vox amp. that doesn't bother me too much though because i have a few nice warm drives in my board. as a lead tone, it sounds beautiful. i would buy this pedal even if it were more than what musicians friend charges
                all it really is is a volume boost. but if you have a nice amp, that's all you need
                the one thing i don't like is that it pops when you turn it on and off. when you're in the middle of playing though it doesn't really matter because it's not that noticible. the pop gets a lot louder though if you have drives turned on in your chain
                built like a tank. i've not seen a pedal so solid before
