Koch Superlead preamp

12AX7 tube guitar preamp and 2 channels: Clean and Overdrive which share the same 2-band EQ and a Boost switch for higher gain. The Overdrive channel magnifies your clean sound with modern gain that can be increased with the Boost switch, for pop to hard rock sounds with sustain. The Pre and Post sound effects loops, before and after the preamp. A 9V DC output protected against short circuits can supply your pedals up to 200mA. Remote input for external controller, balanced XLR output with line level, speaker simulation and ground-lift, jack output with selectable levels.
