Groove

A versatile, transparent onboard preamp designed for more tonal options
while preserving the natural sound of your instrument.
Carefully voiced frequencies and control ranges shape your tone where
it matters most. The Sub switch can transform your instrument from
smooth and refined to aggressive and punchy. The Bass control
provides solid low-end, while Treble adds clarity and presence without
excessive hiss or harshness. The semi-parametric midrange control lets
you select the desired frequency and precisely boost or cut it as needed.
Built to sit at the very beginning of your signal chain, Groove Preamp
lets you shape your instrument’s core tone before it reaches amplifiers,
cabinets, or other effects. When placed after overdrive or distortion, or
anywhere else in the chain, it also works as a flexible EQ, helping you
fine-tune and control your sound.
