From the post
This is a great sounding effect by Dave Barber, modified to put the Sub Bass pot external. Dave sells effects at great prices and their build quality is second to none, so this is one of those builders that everyone should support where possible. So if you get an opportunity to buy any of his other effects at any time then do it, you won't be disappointed.
Info about the original:
Extremely versatile, high gain distortion, provides wider range of stellar tones.
From ultra chunky, to scooped and back to thick again.
Toggle switch selects mid range character for three distinct modes.
Sweet and powerful Vintage two band E.Q.
Internal adjustable Bass Boost for powerful sub frequencies.
True bypass footswitch delivers clarity when bypassed.
All hand wired in the USA, traditional award winning Barber layout and wiring.
Cascading FET circuit, with MOSFET distortion for incredibly realistic tube quality sounds.
