Overdrive pedal based on SansAmp GT2 & Marshall Guv'Nor

This effect was developed due to a couple of wonderful guitar devices: SansAmp GT2 (by Tech21) & Guv'Nor (by Marshall). The Overdrive section were taken from SansAmp and Tone-control (EQ) section were taken from Guv'Nor. The next features were added: hi-impedance (1 MOhms) INput to decrease pickup's signal degradation and bufferred low-impedance OUTput to satisfy any next circuits (long cables, low-impedance mixer's INput and so on). Scheme is deprived next flaws of SansAmp: pops on switching on/off of the effect, strong noise in pauses, no "mid" control EQ.

Coming soon: sound examles ;)
