Essentially, the Retro Super Germanium Overdrive is a fuzz, drive and cranked up amp in one compact chassis. The updated pedal is ultra-responsive and offers maximum dynamic gain.
As the Super Phat Mod is renowned for performing exceptionally well in both low and high gain settings, Keeley has boosted its functionality by tweaking the secondary gain stage to offer a greater dynamic range.
