Treble Booster

Stage-tested by touring pros, this pedal delivers the legendary tones you’ve been chasing. Each unit is built in small batches to ensure quality and a unique, one-of-a-kind voice. For this batch, we’ve paired Telefunken Germanium transistors with carefully selected NOS components, chosen for their rich harmonics, smooth dynamics, and musical response.

The top end is open and articulate, giving you clarity and bite without sacrificing that vintage magic. Designed to capture the classic Tony Iommi early Black Sabbath tones, it excels from soaring leads to gritty, heavy riffs. Whether driving a tube amp or cutting through a dense live mix, this pedal feels like an extension of your playing.
