Get over-the-top drive from an overdrive and germanium amplifier design. The Keeley Retro Super reads your fingers and mind to give you supernatural quantities of gain. The Retro Super is ultra responsive and has maximum dynamic gain. It's a fuzz, it's a drive, and it's a cranked amp all in one!At the heart of the Keeley Retro Super Germanium Phat Mod is our germanium amplifier stage. Designing this additional gain stage into the front of the "amp tone-stack" did wonders because it amazingly simulated a retro-fuzz pedal connected to a cranked amp.
