Bajaman Real Tube Overdrive
Based on the Bajaman Real Tube Overdrive
From the vendor
Bajaman's take on the Tube Driver: TL082 buffer and gain stage into a cascaded 12AX7, with the tone stack reduced to a single Tone control and a 7815/7915 regulated split supply from a 16VAC adapter, which the author borrows for his Overlord mod.
