Featuring the iconic, sturdy Boss chassis, an internal oscillator with seven unique modes, and a four dual-knob control layout consisting of effect/direct, frequency/resonance, and sens/decay. the Boss SYB-3 Bass Synthesizer is a great vintage avenue to real low-end synthesis on a four-string. Capable of summoning sounds reminiscent of Jesse Keeler's work in Death from Above 1979 to the industrial tones of Nine Inch Nails, this is a great pedal to find some experimental tones on either bass or guitar.
