From the post
Zero information around about this circuit. The schematic is signed by Alquinta, and the design looks really nice. Only info i could easily find was the little note on the bottom schematic file: "Bass overdrive with a dirty edge (Low to Med Gain)" The transistors (Q1-Q3) can be 2N5089, BC549C or similar.

So here's one bass overdrive to the library.
