Fulltone 2B Boost Pedal Reviews

Guitar Boost Pedal with Buffered-bypass, JFET Op-amp, and Germanium Diode Limiter

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!

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!

Excellent Boost for Your Pedalboard

By DeVeaux Gauger from Ann Arbor, MI on November 18, 2021

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.

Love This Boost

By Lester Holman from Memphis, TN on October 30, 2021

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.

AWESOME BUFFER AND BOOST, ALL IN ONE

By Mark King from Beautiful Melbourne Florida on October 17, 2021 Music Background: Retired, loving life and my wife

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.

Good Music To You

Absolutely indispensable.

By Eric from Albuquerque on July 26, 2020 Music Background: Blues, psychedelic rock

I've had this pedal for about 5 years and it's easily one of the most important ones on my board. I originally bought it to put before my stacked ts9s to use as a gain boost. It's great in that position, and it works as an incredible transparent gain boost to an overdrive pedal. It's great for that and there's nothing wrong with putting it there, but that's not what this review is about.

I recently moved it to the very end of the signal chain, after my modulation effects. In this position, it does not work as a gain boost for overdrives but rather a volume boost for your whole signal chain. That has some drawbacks if you make extensive use of overdrive stacking, but it's workable. This configuration actually makes it better for a clean boost and gives clean leads a lot more bite and clarity.

I run dual humbuckers with split coils on a 25.5" scale neck-thru with a zero fret (custom from Becker guitars), and I usually run the neck in single coil with the tone up all the way, and the bridge pickup in humbucking mode with the tone at about halfway. With both pickups active this allows for an incredible range of tonal adjustments through the volume knobs on the guitar, and this boost pedal brings out some of the nuances that come out at lower output from the guitar.

I haven't yet addressed this pedal's best feature and why I moved it to the end of the signal chain, which is its unity gain buffering in bypass mode. Basically I like to run my amp clean and turned up, with a lot of headroom. I don't have a lot of effects but currently it's set up as [pitch shifter > envelope filter > wah > stacked overdrives > delay > phaser > multi modulation unit (that I'm imminently replacing with a MDV3) > 2b booster > volume pedal]. This goes straight into the amp, with no rack mounted stuff. This configuration cleans up the pedal signal and also eliminates the need for a buffered volume pedal (expensive pedal from mission or expensive mod from analog man). Since this thing is more than a buffer, it gives you some amazing attenuation options when paired with a volume pedal. I gave up the ability to kick a little more dirt into my overdrive, but **gained** so much more. I'm no electrical engineer but I understand how a signal works. The more components, connectors, and switches you send your guitar's signal through, the more the signal will change. This isn't always a bad thing, but I subscribe to a "less is more" approach and this little booster helps imitate that straight guitar through a 6 foot cable sound, which is invaluable if your clean sound is important to you.

Nothing sucks worse than muddy cleans. Having the 2b at the end of the signal chain cleans up all the junk from the other effects, whether they are on or off and whether the booster is on or off. It repairs all the signal degradation that happens between the guitar and the end of the pedal chain. What goes through the amp is more of your unadulterated guitar tone, and that is truly a priceless thing to have.

Great Boost pedal !

By Dave T. from Wisconsin on August 23, 2019 Music Background: Professional Tone Tweaker

Great boost pedal, I have it right after my compressor. It gives me that extra something for my Strat...
Buy one , You wont regret it.. And Ben got me hooked up !

Give yourself a nice little boost.

By Craig Keefer from SC on January 4, 2018 Music Background: I play a lot.

Nice! The 2B sounds great - because it doesn't really sound like anything. It does give a little extra "sparkle" to the boost, especially when you turn up the "Dynamics" knob - but it only serves to help break above the rest of the band, in the way you want it to. It's pretty narrow - which can be a little bit of an issue when you step on it. But the wedge shape keeps it stable enough (although it would be hard to stomp if it were nestled between a couple of tall pedals). Mine is the last thing in my signal chain, right after a loop switcher. This lets me boost anything going through the looper, and lets me take advantage of the built in buffer, when the 2B is "off".

Great boost!

By lefty 54 from central NY on July 29, 2015 Music Background: guitarist

I was looking for a buffered bypass signal conditioner for my pedals and this one delivers. The fact that it's an excellent boost is just icing on the cake. But the boost feature has changed my way of looking at my entire rig. With the gain just past unity--around 9 o'clock--it adds amazing sparkle to my tone. Everything I had, just a little bit bigger, clearer and sharper. Full disclosure: I haven't experimented with the boost fully cranked yet, so I can't comment on how it performs overdriving the amp's input, but that's not what I got it for. And I'm just scratching the surface of the dynamics control. Also, I only tried it with a couple pedals in the chain, but so far it's amazing. Natch, Derek made sure it got here in record time. Can't say enough about Sweetwater's Customer Service. If your pedal chain needs a kick in the tail, give the 2B a shot! I used it at practice last night and it was 'always on.'

Good boost pedal

By Mike from RI on May 12, 2017 Music Background: Amatuer musician/hack

Great boost pedal for what it is. Small enclosure means you can only really fit a few knobs on it. Does a great job of adding a little hair to your signal. I use it mostly to push clean channels into the verge of break up. Can also push already distorted tones into further saturation for solos. Dynamics knob probably does something but it's hard to tell. I use two different boost pedals in my chain. This one and another one with bass, treble, volume, and gain controls. The other one is obviously more versatile, but this one is smaller and works very well.

need a boost?

By Tony from North Carolina on August 19, 2015

nice organic sounding boost and dynamics knob make it mo eggzelent,will never leave my pedal board

Handy clean boost

By JS from CO on July 5, 2016 Music Background: Multi-instrumentalist

As a boost pedal and buffer it sounds great and does what I need. The volume knob has the right taper and range. It is easy to dial in just the right amount of boost. And the boost is clean (no coloration).

I occasionally play instruments with ultra-high impedance piezo pickups. The 2B will be useful for those things.

The dynamics section is so subtle that even full-on, I don't hear it doing anything. Inside the battery clip is VERY stiff and tight; so much so, it is difficult to get a battery in or out. I thought I might break the thing just swapping out the included battery. That said, it is built like a tank, it sounds good, doesn't add any noise and it is versatile. I'm happy with the 2B.
