Kharkiv CMOStortion

MT-10 inspired drive unleashed, delivers vintage grit



Kharkiv CMOStortion is our take on Ibanez MT-10 Mostortion OD circuit. However, it's not just a clone but an improved version using NOS (new old stock) and high-quality components with a discrete op-amp gain stage instead of CA3260 without diodes and input buffer. Discrete op-amp followed the basic structure of CA3260 MOSFET inputs and CMOS outputs and has a single green LED for asymmetrical clipping.


  • Drive - gain level.
  • Level - output volume.
  • 3-band EQ - passive Bass/Mids/Treble EQ, which is quite unique to Mostortion.
  • LED brightness trimmer - placed on the PCB trimmer allows you to adjust the status LED brightness.
