From the post
Requested by loads of people. I originally thought this would be a job for PCB, but after several more requests I had a think about it and estimated this may just about fit is a 1590B if I was careful. It turns out it will fit more comfortably than I expected. It will probably still need to be mounted with components facing down, especially with the dual log pot, but it'll still be fairly comfortable IMO.
Info from Boss about their original:
The BD-2 Blues Driver delivers the creamy, yet crunchy sound associated with great blues guitar. This popular pedal provides instant access to the kind of warm overdrive and emotive distortion usually reserved for 30-year-old tube amps.
Classic "blues" guitar tones with tube amp simulation Warm distortion and overdrive Responds to nuance and volume changes

- 2M: three resistors are read as 2M/1M-class values; the two read as 2M (left edge near Tone 3, and right of the 470K under Q7) are small and could be confused with 1M at this resolution
- 1u bottom centre is drawn as a film/box capacitor, not a can, so it is not marked electrolytic
