Used Keeley Custom Shop Limited Edition XVIII Space Trio Germanium Overdrive Pedal

The Keeley Custom Shop Limited Edition XVIII Germanium Overdrive is what happens when Robert Keeley and his team of Oklahoma mad scientists decide to celebrate their 18th anniversary by building a "Klon-killer" and wrapping it in a gorgeous, highly collectible custom space-themed aesthetic.

To build this stompbox, Keeley took their legendary Oxblood circuit, stripped away the harsh clipping, and added a hand-selected germanium transistor directly to the output stage. The result is an incredibly bold, uncompressed, and organic overdrive that perfectly mimics the dynamic, saggy feel of a cranked vintage tube amp. Running on an internal voltage-doubler for massive headroom, it delivers throatier, more musical midrange and a touch of second-order harmonic sweetness that completely rounds off any ice-pick frequencies.

This limited-run Custom Shop beauty gives you absolute surgical control over your gain structure with a highly interactive, 5-parameter layout. The Phat Switch lets you cut or boost the low-end response to transition seamlessly from a classic, mid-focused TS-style scream to a wide-open, bass-heavy roar, while the Clipping Switch lets you choose between pristine, touch-sensitive saturation and flat-out singing sustain. Whether you want a clean, high-headroom boost to push your favorite tube amp over the edge or a fuzzy, thick distortion that reacts beautifully to your guitar’s volume knob, this hand-built, limited-edition powerhouse is a premium tone-shaper that deserves a permanent home on your board. This pedal is in good condition and ready for you!
