Fulltone 2B

The Fulltone 2B is an ultra simple clean boost and buffer pedal.

This is essentially just the boost element of the Fulldrive 3, carved out and put in its own box, making it a great value pedal.

Fulltone says:

“The Fulltone 2B is a tiny, transparent, and amazing BUFFER/BOOSTER  pedal, born from the “Boost” channel in our FD3 pedal.

Soon after the FD3 came out I started getting a steady flow of emails asking if I could “please make that into a single channel Boost pedal!”

Its not just a simple boost, however. The circuit is designed with a dynamics function that enhances dynamics to improve responsiveness without the associated overload and harshness.

Gives up to 20dB of boost

When switched off, the buffer element will  drive long cables when the pedal is switched off and need a not a separate buffer.

This is a very musical clean boost pedal, with subtle compression and limiting to maximise your signal and improve your overall tone.

It is not true bypass..it’s even better, it has our enhanced JFET bypass.  So,  even when it’s off it is the most transparent, natural sounding buffer pedal you’ll ever hear!

I crammed the circuit into the smallest possible enclosure 4.5″ x 2.1″ x 2.3″ . The battery is tucked tightly inside and even engineered space-saving rear-mounted IN, OUT, and DC power jacks.

Why does a guitarist need a “Boost” pedal?

A boost pedal is not only used to kick up your volume when it’s time for your solo!

A good booster can also solve a lot of problems in the modern guitarist’s rig, because today’s pedalboards average 8 or more pedals.

With each of those pedals requiring: a guitar cable; jack; more wire; footswitch; circuit; footswitch again; jack;more wire and on to next pedal!

It’s a wonder there’s any signal left after all the stuff we put our signal through.

Ever played through a 10’ guitar cable straight into a great tube amplifier? The feel, the dynamics, the fat tone makes you want to play!

Then you connect to your overpopulated pedalboard and suddenly the sound is tiny and because of the diminished lows and dulled highs.

This is where a good booster comes in handy. Because all that wire and all those connections reduce your signal by a measurable amount with each passing effect in your signal chain.

Add a good booster and you can recoup a lot of that lost gain, tone, and reactive interplay between you and your lovely tube amp. Suddenly the “touch” is back


Self explanatory – Gain,


What’s the DYNAMICS knob?

The 2B offers something completely unique in the world of Boost pedals; a DYNAMICS knob.

A subtle Germanium diode limiter circuit that (as you turn the min-knob clockwise) starts to slightly alter the feel of the notes being played. It also subdues the harsh transient spikes which can overload your amp’s input.

Those spikes can be fatiguing to your ears, to the amp, and to its speakers!

Similar to using a limiter on the mix down of a song in the studio, the 2B’s DYNAMICS feature helps you keep your place in the live mix, .like a very smart compressor.

This feature can make even an “ok” amp feel responsive and juicy, and will keep you from distorting the amp’s input, a problem plaguing most booster pedals.
