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.
