Soundblox Guitar Envelope Filter

The Soundblox Guitar Envelope Filter brings funky auto-wah and filter effects to guitar. Envelope following responds to picking dynamics for expressive sweeps that react to your touch.

Multiple filter types and sensitivity controls shape the response character. Adjust attack and decay to dial in everything from quick quacky funk to slow, sweeping textures. The technology established Source Audio's filter expertise, later refined in the Soundblox 2 Stingray and One Series Spectrum.

Compact enclosure with straightforward controls makes dialing in sounds quick. 9V DC operation with true bypass switching ensures clean tone when disengaged. A solid introduction to Source Audio's envelope filter technology.
