"Rupert" bass overdrive preamp with two outputs
The Rupert Bass Overdrive is a fat sounding tubelike preamp and overdrive for Bass Gutar.

Rupert is a multi stage FET preamp with gain staging and Germanium diodes that sounds and plays a lot more like a bass guitar amp than a pedal. It is a very responsive bass overdrive that can go from warm semi-clean tubelike bass tone to the '60's era arena rock fuzz driven crunch tones. It's a great pedal for Rush, King Crimson and King's X tones.

The amazing thing about the Rupert, is that it provides the dynamic touch response of a vintage tube amplifier. It makes a small bass amp sound massive. It's like a tiny Concert Arena for your bass guitar!

ABOUT GAIN STAGING: Discrete preamps provide gain in several stages, so that a lot of what happens to provide the right amounts of drive and compression in a preamp is determined by how many discrete stages are employed, and their levels, determining how the stages interact.


The Rupert is THE pedal for bass players, adding a rich sounding tube-like touch to your sound. Output 1 will have the true-bypass-switchable Rupert effect, where output 2 has an "always on" FET preamp for direct recording.
