$175.00

Description

Kavun MOS Drive takes the foundational EQ of the Ibanez Mostortion and builds a totally new, unique overdrive experience. Unlike its inspiration, the Kavun MOS Drive uses a discrete MOSFET op-amp and input buffer. This custom op-amp works in tandem with asymmetrical Germanium diodes and a MOS transistor to create a highly distinctive overdrive texture you won't find anywhere else. The result is a pedal that delivers everything from transparent, dynamic boost to a rich, harmonically complex drive, all while retaining a familiar and powerful EQ section.

Controls

  • Volume - output level.
  • Resonance - controls boost/cut level of two peak filters: 500Hz and 800Hz.
  • Drive - gain level, from boost to mid-gain overdrive.
  • Volts toggle - switches circuit voltage operation between 18V and 30V.
  • Mode rotary - switches between 6 clipping options: Boost (no diodes, raw op-amp clipping), LED (2 red LED diodes), MOSFET (2N7000 transistors), Si (2 vintage Silicon diodes), Ge (2 NOS Germanium DG-51 diodes), Asym Si (3 modern Silicon diodes arranged for asymmetrical clipping).
  • LED brightness trimmer - placed on the PCB trimmer allows you to adjust the status LED brightness.

About the name

The "Kavun MOS Drive" is a pedal with a rich story, inspired by our friend, the Kyiv-based guitarist and teacher known as Denys "Topor" (Axe) Toporchuk. He frequently uses a Kharkiv CMOStortion pedal, which forms the foundation of this circuit. The name "Kavun," which is Ukrainian for watermelon, comes directly from his band's (Pivas) single, "I want a watermelon" (Хочу кавуна). This name also pays tribute to the Kherson region, which is famously symbolized by its watermelons, a registered national brand and a powerful emblem of the region's identity and fortitude.
