From the post
Came across the schematic for this and thought it would be a good addition. It's a unique germanium overdrive using PNP AC128s, though the effect is a negative ground effect (so it can be daisy chained with other pedals). The TA-100 has been used by Ryan Adams and sounds great through a Princeton Reverb. Schematic here on FSB.
