A good treble booster doesn’t just add top end

It shapes your mids and upper harmonics so your guitar sits where the vocal and drums won’t swallow it. That’s the Chorister: a single Level control, classic feel, and the right kind of bite. Choose your flavour. The Chorister Germanium serves dynamic, vintage‑voiced lift that blooms as you dig in. The Chorister Silicon delivers a tighter, punchier edge with the same mix‑cutting focus. 

Both are built to hit the front of an already‑driven amp, where they wake up your valves, add grip to picked notes, and unlock singing sustain without mud. Think of the greats often linked to treble boosters: Rory Gallagher, Brian May, Tony Iommi, Marc Bolan, Billy Gibbons. Different rigs, shared intent. Presence, articulation, authority. A booster that lets you keep your guitar’s character while projecting clearly across a loud stage.
