The Grayskull is based on the idea of the "Life Pedal" that was released by EQD in 2019. A great pedal but a couple of things were missing resp. not optimal for endless doom/drone sounds.

The Grayskull is based on the classic rat circuit. An additional gain stage is following and surrounded by an active clean blend.

Apart from the dirt section, the Grayskull features a digital and blendable suboctave (polyphone) that can be activated by a second footswitch. You can also use the octave without the distortion but with all the other pedals on your board!

Das Pedal ist in einem kompakten Gehäuse für den Einsatz auf Pedalboards untergebracht. Es richtet sich an Spieler, die dezente bis moderate Modulationseffekte suchen.
