A revelation. Stripped down all out amp pusher. The Revelation has a trio of controls. Pre Gain, Gain, and Volume. LOTS of volume. Pre Gain sets the overall gain level of the device, the gain control dials in the correct amount of distortion and the volume knob absolutely slays the front end of your amp. Think of the Revelation as an extension of your amp’s pre section. Use it to push your amp into super creamy saturation, use it to boost your riffs into full and thick exaggerations of your amp’s base tone. The Revelation does not alter your tone, just makes MORE of it. Choose the Revelation to hammer your amp.
The SuperBass version of the Revelation is a rounder, more dynamic take on the circuit. A bit bassier, gruffer, throatier sound. Works equally well for guitar or bass, choose the SuperBass for a fuller, fatter sound.
After looking at the schematic it seems like a really stripped down big muff, and I mean stripped down. In particular it's basically the Pharaoh without the tonestack.
