The Aclam Windmiller Preamp is a boutique preamp pedal based on the preamp circuit of the Grampian Reverberation Unit Type 636 (S/N: 1138) — the very unit Pete Townshend used as a saturation tool to shape his legendary guitar tone. Versatile enough for guitar, bass, and keys, it works equally well as an always-on tone enhancer, a clean boost, or an overdrive catalyst.
Run it as an always-on preamp for beautiful tonal color, engage it as a booster for solos, or use it to push your amp's natural overdrive into new territory. The Hi/Lo Cut controls let you dial in exactly the right frequency balance for your rig.
