I'm looking for an accurate and legible schematic for the Boss BD-2 Blues Driver.
Of the two schematics doing the rounds one is a really bad photocopy and I can't make out
the transistor values and the other one is from gaussmarkov and just has generic listings
for the transistors.
Can anyone please help?

Welcome to the forum,

The discrete opamp pnp BJTs are 2SA1335-GR.
The discrete opamp JFETs are 2SK184-GR.
The two JFETs for the switches are 2SK118-Y.
All npn BJTs are 2SC2458-GR.

I hope that helps, if not let us know.
