Classic 1970s Auto-Wah Dynamics with Modern Boutique Performance

The Guitar Sanctuary is proud to offer the Seamoon FX Funk Machine Envelope Filter Pedal. Originally designed in the early 1970s, the Funk Machine earned legendary status as the secret weapon behind some of the most iconic bass and guitar riffs in funk, soul, and R&B history. Re-engineered by Seamoon FX, this modern production pedal captures 100% authentic, organic analog envelope filtering while adding crucial control upgrades for today's pedalboards.

Handcrafted using an upgraded low-noise analog circuit, the Funk Machine responds dynamically to your pick attack and finger dynamics. Featuring an integrated Pre-Amp Gain stage, a dedicated Frequency Sweep Control, and a fine-tuning Presence Control, this pedal seamlessly handles everything from vintage passive single-coil guitars to high-output active basses without losing low-end punch or clipping unwanted frequencies.

Sanctuary Expert Take:

"The original Seamoon filter defined the funk bass sound for guys like Larry Graham and Bootsy Collins. This reissue hits that exact liquid envelope response, but the added Pre-Amp and Presence controls make it far more versatile for modern pedalboards and active pickups."
