Koch 63'OD Preamp Pedal – 2-Channel Tube Preamp with Boost, FX Loop, and DI

The Koch 63'OD is a professional, tube-driven preamp pedal that brings the legendary guitar sound of the '60s to your pedalboard. Featuring two fully independent channels (Clean & Overdrive), a shared 3-band EQ, and a powerful Boost function, this preamp is ideal for studio, rehearsal, and live use. The Clean channel offers a clear, neutral tone, while the Overdrive channel delivers warm, saturated midrange inspired by iconic blues and rock sounds. The OD Boost provides that extra boost for solos or more intense riffs.

The 63'OD is equipped with pre- and post-FX loops for maximum flexibility in your signal chain. Thanks to the balanced XLR DI output with speaker emulation, you can easily connect it to a mixer or audio interface. The pedal also includes a 9VDC output for powering additional pedals, a monitor output with three level settings, a connection for external switching devices, and a rugged aluminum housing. In short, a compact and versatile tube preamp for guitarists who want to maintain their signature sound anywhere.
