Dinosaural OPA-101 Overdriven Pre Amp

 Just traced by Aion Fx as their Ixuea project. This layout is slightly modified compared to the original pedal. First, stock units had a fixed low pass filter before the volume control. The resistor in the filter is now replaced by an external tone control. Secomd, it is wired for true bypass with the input buffer hardwired.
