Boost Your Performance and Save Your Tone

Utilizing the same JFET op-amp as their wildly successful FD3, Fulltone’s 2B guitar boost pedal is your secret weapon for musical domination. Imagine yourself onstage. The crowd is stoked. Then it’s solo time! You stomp on the 2B to kick your tube amp up a notch. The feel, the dynamics, the fat tone — they’re all there. The result? A lot of love from your audience! The 2B also preserves all your gain, tone, and reactive interplay when you play through an overpopulated pedalboard, rescuing you from the tiny, thin sound you’d typically experience with stompbox overload. You’ll find a quality boost pedal like the Fulltone 2B on nearly everyone’s pedalboard here at Sweetwater. So what are you waiting for? Your audience awaits!

Rescues your tone from an overpopulated pedalboard

Do you have a massive chain of stompboxes? If so, all that wire and all those connections reduce your signal with each passing effect in your signal chain. The result is a tiny, thin sound with wimpy lows, cardboard mids, and scratchy highs. Well, you don’t have to let your overpopulated pedalboard emasculate your tone. Put a Fulltone 2B guitar boost pedal in your chain and win back the lost gain, tone, and reactive interplay between you and your amplifier. You’ve got the touch — you’ve got the power!

Unity-gain JFET op-amp buffers your signal when the pedal is bypassed

Low-quality boost pedals cease to offer a high-quality unity-gain buffer when you shut them off. This becomes especially problematic if you’re driving a long cable. One solution would be to buy a second booster, set one to unity gain and use the second one for your volume changes. Well, who wants to do that? The Fulltone 2B guitar boost pedal solves this dilemma by utilizing its unity-gain JFET op-amp to buffer your signal when the pedal is turned off. The only thing that changes when you turn the 2B on is that its Gain knob becomes active, allowing you to boost your signal by as much as 20dB.

Gain knob reduces harsh ultra-high frequencies

Some boosters sound a bit harsh when you crank their gain. The Fulltone 2B guitar boost pedal compensates for this by subtly rolling off of the harsh ultra-high frequencies as you roll the Gain knob clockwise past 12 o’clock. This doesn’t drastically affect your tone; however, you won’t have to worry about hearing that shrill top end that lesser boosters can impart!

Dynamics knob subdues unpleasant transient spikes

Transient spikes can be fatiguing to your ears, your amplifier, and your speakers. That’s why the Fulltone 2B guitar boost pedal sports a germanium diode limiter. As you turn the Dynamics knob clockwise, this innovative circuit subtly subdues the harsh transient spikes that can overload your amp’s input. The 2B’s limiter not only helps you keep your place in a live mix, but it also makes your amp feel responsive and juicy without distorting its input.

Fulltone 2B Guitar Boost Pedal Features:

  • Preserves your tone when playing through a large effects loop
  • Buffered bypass to maintain unity gain when pedal is bypassed
  • Level knob reduces harsh ultra-high frequencies
  • Germanium diode limiter subdues unpleasant transient spikes
  • Ultra-high 1.65 mega-ohm impedance eliminates interaction issues with guitars or other effects
  • Ultra-low 300-ohm output impedance eliminates loading or interaction issues

Simple and Solid

Plug a great instrument in and a pure sound is what you'll get. The perfect boost pedal.

Fulltone 2B Boost Pedal

Great boost pedal, worth every penny!
Rated 5/5

Excellent Boost for Your Pedalboard

This pedal is an essential part of my pedal board. Allows me to get a simple easy volume boost without changing anything else. Great when you're playing clean rhythm and go into a clean lead to get some extra boost without using other f/x that change they sound.
Super simple, set the level and on/off button. Completely transparent in off or on, has a built in signal buffer, and all this in a compact package that doesn't take up much space. The Dynamics knob provides some limiting, which is a good feature.
Highly recommended addition to any pedalboard.
Rated 5/5

Love This Boost

It's great. Just don't tell Fuller. Used on the same pedalboard with a Naga Viper treble boost. I use the 2B more often, but they are different animals with different applications. This pedal is just a straight boost with a bit of leveling compression if you want it...the Naga Viper is a Rangemaster on steroids. Different animals.
Rated 5/5

AWESOME BUFFER AND BOOST, ALL IN ONE

This is one of Mike Fullers better pedal designs, it's simple, innovative, compact and sounds fantastic.

When you have your guitar plugged into the input it is turned ON as a buffer pedal. The knob does nothing in buffer mode. As a buffer it can isolate your guitar from 100+ pedals in series and maintain your tone. Push the foot switch and the GAIN knob becomes active giving you an adjustable level boost. The 2b provides unity gain Buffer with Footswitch Off or Boost with Footswitch ON.

This dual function (buffer and or boost) can be immensely useful when you use a guitar with electric and acoustic outputs where the acoustic is a little low in level. I make up for that level difference with the Boost function and use this pedal normally as a unity gain buffer (the first thing my guitar plugs into).

I have two of these now to cover all my applications, I'm getting ready to order a third one. I've considered some other boutique boost pedals but none have this unique combination of compact, Buffer and Boost.

The Fulltone 2b can run on an internal 9-volt battery or 9-18 volts through the external power inlet. I don't hear any difference at 18 volts and I don't like that voltage floating around pedals that can be destroyed if someone accidentally plugs 18 into a 9-volt-only hole.

One of Fulltones best and most useful pedals.
