Fueled by premium germanium diodes, the Keeley Manis takes the half-equine star of the overdrive pedal pantheon to new tonal heights. Whether you’re juicing the front end of your amplifier or cranking up the Drive knob into high-gain horseplay, the Manis supercharges your sound without compromising your core tone’s character. Moreover, the Keeley Manis goes well beyond the standard take on the legendary ’90s-era overdrive — Robert Keeley augmented the original pedal’s circuit with the ability to swap from its treasured germanium diodes to a set of Cold War-era germanium transistors. This appealing addition unlocks a stampede of thick saturation, powerful sustain, and lively tube-amp-like responsiveness. On top of that, Keeley upgraded the Manis with a Bass+ switch that kicks up your signal by 3dB and lowers the frequency response by one octave for fuller, fatter drive sounds across the board. Complete with a switchable true bypass/buffered bypass silent switch and the ability to run at 18V for enhanced hi-fi headroom, the Keeley Manis enables you to take the reins of the most mythologized tones in guitar history.
