Have tried FB-2 for half an hour and the first impression is that it´s a great pedal, really expressive.
The boost section has a wide range of sounds, from clean boost to heavy mid boost, and all settings sound good to me. This is the most versatile booster I ever tried. It can create great feedback tones without engaging the feedback section, with the right amount of volume on the amp.
Kicking in the feedback gives a rising volume before the feedback occurs, very natural sounding. Great sounds when bending strings!
The feedback function works best when there is some volume at the amp, I suppose it works together with the speaker and this makes the sound very, very natural. In a way it acts like a booster within the booster. Together with the four knobs there are a lot of variation.
The feedback section can´t be runned alone, the booster kicks in at the same time. Not a bad thing as it would sound unatural when suddely a feedback tone would jump out from a low volume sound.
When the foot pedal is released the feedback quits abrubtly, well this could be better, but the way around this is to take a new note before releasing.
Compared to DF-2 the feedback made FB-2 is much better, much more natural sounding.
A great peadal from Boss and the first booster ever, if we don´t count the boost setting of FZ-2.
Edit: Now I´ve used it with OD´s, distortions and fuzzes, with even greater result. The feedback section shines here, I could get infinite sustain at very low levels, great for bed room playing.
Booster/feedbacker before or after dirt boxes get different results, of course, and there are a lot of experimenting waiting.
The feedbacker, I think, uses a heavily set compressor and a gain stage, you could actually get the sound of a CS-1 here. So it´s nothing very un-natural to the sound, just a compressed sound.
This pedal is a very funny to "play" with
