B-301 Tube

The B-301 Tube is an overdrive from Big Joe's analog B-300 series, voiced after the screaming tone of a pushed tube amp for classic rock and blues. Its responsive gain structure keeps notes clear and dynamic rather than muddy as you dig in, tracking pick attack and guitar volume so it cleans up when you roll back.

Three controls keep it simple: Gain sets the amount of drive, a mid-range-sensitive Tone shapes the voicing, and Level sets output. It works as a light, edge-of-breakup rhythm drive or a fuller lead overdrive in front of an amp. True bypass, powered by a 9V battery or a standard 9V DC center-negative supply.
