Turn your regular amp into a Full blown, multi channel Tube amp with this Full Tube preamp/Overdrive from Koch!  Koch's tube-powered guitar preamp with classic vintage overdrive, OD Boost, and maximum functionality!  Comes with power supply!  We already knew the Koch Pedaltone, but this one offers more and has a smaller footprint! 

The Koch 63'OD is much more than an overdrive pedal. It can be used not only as a normal effect pedal, but also as a preamplifier. You can therefore connect the 63'OD directly to a power amplifier. In addition, the 63'OD's overdrives are driven by a 12AX7 tube, which guarantees warm and organic sounds. And of course you can expect nothing less than top quality from Koch. The 63'OD is a stompbox that is derived from the Koch Pedaltone, but focuses specifically on milder, more bluesy overdrives.

Note that 99% of the known overdrives are solid state effects trying to emulate the tube sound. This Koch '63-OD does not emulate. It is the real deal! There is a real 12AX7 tube doing the work here! 

The 63'OD has two independent channels (Clean & Overdrive) which share a 3 band EQ, plus a Boost switch for higher gain. The Clean channel is focused on clarity and full-frequency response to accurately reproduce your guitar's tone. The Overdrive channel fills in your clean tone with the thick tube-driven mids and saturation that made legends out of guitar slingers in the 60s and 70s. 

The Koch 63'OD also features both pre and post FX loops for adding tone shaping pedals before the pre-amp, and modulating pedals after the pre-amp. There is a 9VDC output that can power your additional pedals up to 200 mA, (so place it on your pedalboard and power for instance your tuner, and two or three more pedals) and is fully protected against short-circuiting. The remote control input can be used with midi switchers or other external switching devices. Finally, there is a balanced XLR DI output with line level signal, speaker-emulation and ground-lift for connection to recording or mixing consoles, and a 1/4" output with switch-able levels for connection to any type of amp or monitor.
