The Steve Vai Legacy Tone Capsule is a modification circuit that re-voices the tube circuit characteristics of the original Waza Amp. BOSS engineers worked closely with Steve to produce the ideal compression on each string and precise audio response at any volume. Injecting key elements of the Legacy amp, the Tube Logic circuit modifies the tone to produce Steve's signature sound. From smooth sustaining lead tones to warm, wide, and dynamic clean response, the Steve Vai Legacy Tone Capsule embodies that iconic sound.
