Discover one of rock guitar's best-kept secrets.
The Aclam Windmiller Preamp is inspired by Pete Townshend's unconventional use of vintage Grampian spring reverb units as a tone-shaping and amplifier-driving tool during the mid-1960s. Rather than using the units for reverb, Townshend pushed their preamp circuits to drive his amplifiers harder, creating the powerful, dynamic sound that helped define an era of British rock.
Aclam carefully studied this unique approach and transformed it into a highly versatile preamp pedal that captures the character, response, and musicality of the original concept while providing modern reliability and flexibility.
The Windmiller excels as an always-on tone enhancer, a transparent boost, or a way to push an amplifier into rich harmonic saturation. Dedicated Lo-Cut and Hi-Cut controls provide extensive tone-shaping options, allowing players to tailor the pedal to virtually any guitar, amplifier, or recording setup.
Whether you're looking for additional clarity, vintage-inspired drive, enhanced dynamics, or a powerful front-end boost, the Windmiller delivers exceptional versatility while preserving the natural character of your instrument.
Hand-built in Barcelona, Spain, the Windmiller combines boutique craftsmanship with one of the most fascinating tone stories in classic rock history.
