The Boss BC-2 Combo Drive overdrive/distortion category offers three voices that can be dialed in with the pedal’s Sound, Bass, and Treble controls, while the Level controls overall effect volume. Boss’ FB-2 Feedbacker/Booster combines an adjustable tone/gain boost with the ability to engage feedback on-demand. It has controls for Boost, Level, and Tone, and a Character knob that adjusts treble boost. The pedal’s Feedback knob tweaks time taken to boost the point of frequency to feedback.
