Very versatile booster

Sometimes you want to step out in the mix, but just a little bit for a little solo or something and there is not enough time or skill to do it by turning up your volume knob. That's where a booster typically comes into play. This one is a very versatile example of its art because you can dial it in as a clean boost, a mid-range or as a treble boost. There are also some nice in between spots to check out. It also has a function to generate feedback, from a soft low background drone to a high terrific scream, that's mainly a gimmick, but it can be useful if you want to have an instant feedback without the hustle in front of your amp. The problem with that is, that the decay of feedback is too harsh, when you leave the pedal it vanishes immedeatly and there is a short but recognisable drop in Volume right after that. That makes it a good 4/5 to me.

Nice Boost Pedal With Added Feedback Capability

There are two kinds of guitarists: those who prefer a transparent boost, and those who don't mind a little color in their signal. The Boss FB-2 seems to come up somewhere in the middle, oddly enough. It's nowhere near as clear as, say, the MXR MicroAmp--probably due to Roland's buffer--but at its mildest EQ setting, it's much more difficult to hear than you might expect.

The secret sauce here is the Tone knob, which allows the user to dial in anything from a flat (non-EQed) signal to a bold midrange hump, up to more extreme settings. And actually, with the Tone knob at 12 o'clock, the pedal can really fatten a guitar's sound and really help it cut through a mix. This is especially useful with single-coil guitars, like a Fender Strat, which can sound thin in the context of a live band.

This pedal has a few other neat tricks up its sleeve. Most obviously (since it's part of the unit's name), it can assist in the generation of feedback when the pedal is held down. It does this by raising the volume slightly, and the nature of the feedback generated varies depending on where you position the Feedback knob. In my experience, the noise floor and volume increase substantially the higher you set this value; however, that can be a desired effect in certain circumstances. The lower half of this dial can be used to summon nice, droning waves at fairly low volumes, making it extremely useful in small gig or practice settings.

Another nice aspect of the FB-2 is that, with the Boost and Character knobs set sufficiently high, the pedal begins to act more like an overdrive pedal. It has a more harsh character than, say, the SD-1 or a Tube Screamer, but it's not unpleasant--in fact, there are times when I find myself using the pedal specifically in this way, rather than engaging my super-smooth Fulldrive II MOSFET. I like the "clang"-y nature of the FB-2's driven tones; they're reminiscent of classic punk and post-punk records, to my ears.

In short, this is a cool pedal with a fair amount of sounds to be explored. Highly recommended.

From Gear Setup

Clean boost, and great feedback effect. Love having it at my feet.

I know a local player who swears by his Sustaniac pickup with the volume knob that clicks into feedback on the "11" setting. All that is nice, but having the feedback effect at your feet allows your hands to remain free (to play notes). I find the FB-2's feedback effect is perfect for when you need a controlled feedback, for example if you just need it for the last couple beats of a phrase. Instead of running back to the amp and hoping to hit that sweat spot on stage you can rest assured knowing the FB-2 has you covered. Also, if you don't have a wah or heavy distortion going, the FB-2 gets you that feedback regardless. It's definitely useful and sounds good in a band mix. The boost is great, too. Whenever I am playing a small gig, or sitting in with some friends, or going direct into a cheap PA system, I use the boost to get nice lead volumes. Many times in these settings the FB-2 is the only pedal between my guitar and my amp (or DI box, PA head, etc). I am not a huge Boss player, but I love this pedal and recommend you try it before dismissing it. It's one of my best "secret weapons."

BOSS FB-2 FEEDBACKER BOOSTER

"I have used different of boost pedals and this is my weapon of choice. It's a two-in-one pedal. You can create unstoppable feedback for some dynamics and you can boost your sound. The unique thing about this pedal is it has the Tone Knob which you can dial-in your preferred boost sound. If you want a fatter boost sound, setup the tone on the low. If you want a mid-focused boost, set it up on the center. If you want a sharp and edgy boost, set the tone knob on higher settings. Plus you can use this as a clean boost or a dirty boost. I like pedals which has a lot of options."

Great Boost Pedal

The 'boost' part of this pedal is good, and the character knob is nice for lead breaks and solos. A bit of tweaking and you can actually use this as an overdrive as well. I don't care much for the feedback function however, it doesn't sound at all like natural feedback to my ear, and I found it a bit awkward to use in a live setting.

This is a must for clean boost and Controlled FeedBack

lot of expression, it seems to have a mini equalizer in it to produce some more gain to boost cleanly and also a "mid" to "hi mid" range and also a filter to keep the signal as clean as possible and also to correct the resonance. Try it and listen the color of the sound according the settings , very surprising and great in sum. The feedback is completely controllable, you can play with layering of feedback plus the signal you play

Great booster with a secret weapon

The FB-2 works great just for a little boost and volume to make you stand out during a solo or to beef up a particularly intense part of the song and, in the same vein, it works pretty well as an overdrive pedal. The thing that sets it apart and makes it a fun little toy in your kit is the eponymous feedback feature. Feedback can be hard to master and control, but even at low volumes the FB-2 does a pretty great job of emulating that feedback and putting it in your control.

My soul in a pedal

My first pedal bought blind. This is one of the loudest things I've ever heard. Like without long cabling and without buffers, just on its own to your amp, you have a hard time putting the level over 25%. Momentary feedback stomp is the main thing that adds on top of the good mid boost overdrive. This is just fun fun fun.

You don't think you need it, but you probably do.

Got an amp that you think is cool? This makes it cooler. Holding it down makes a feedback loop. Trust me, you'll have more fun with it than you think.

Very nice boost

Don't have it anymore, but it is nice to be used as a boost with a tone knob to shape it. The feedback function is interesting depending on your style /music.
