This is one of my preamp designs, I call it the Overdrive Extreme. It is designed to be a small pre-amp capturing the big tones of the Dumble ODS amp. The circuit is a mix of solid state (JFET) and vacuum tube. With many controls and features the tones are highly flexible.

Top Drive is very much like an old Vox AC30 in the sense that is has a single volume control.
