Turn your regular amp into a Full blown, multi channel Tube amp with this Full Tube Overdrive from Koch!  Koch's tube-powered guitar preamp with classic vintage overdrive, OD Boost, and maximum functionality!  Comes with power supply!  

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 those additional pedals up to 200 mA, 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.
