Synth-1 Reverse Attack Fuzz Wave Generator


Our Synth-1 is now available in a Custom Shop 20 for 20 ‘Trooper’ White finish, complete with 20 for 20 Keeley Custom Shop insignia. This color way is limited to 20 pedals, so be sure to pick one up before they’re gone forever!

The Synth-1 allows you to create fuzzed-out synth waves!  Use the Filter and Blend controls to mix your guitar with the fuzz from the synth.  Go from churning slow-gear reverse swells to sounding like a light saber.

The Keeley Synth-1 is a guitar-triggered, single-note wave generator.  You control the tone of the wave with the Filter Control.  The lead-in time or swell of the note is controlled with the Attack knob.  Then use the Blend control to remove the natural tone from your guitar as you slide through synth-sounding fuzz waves.  Use an expression pedal to control the Filter, and now you have Wah-Wah-like control of the Synth-1.
