Boost Your Performance and Save Your Tone

Get to know them!

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
