Dunwich Amplification Modified HM2 - DIY version

 Dunwich released a small run of DIY PCBs a few years ago of a modified HM2. There is a few changes from a stock HM2 most noticable the on/off switches for both soft clipping and hard clipping diodes. You may want to experiment with the cap values at one of the gyrators for a more effective separate Mid control. AMZ and Griffin Effects have very useful bandpass filter/gyrator calculators.
