Got a request for this one. It's apparently a modified Bogner Ecstasy Red, which is a JFET adaption of the Red channel on the Bogner Ecstasy amp. Since it uses 2 footswitches, I went ahead and designed the board for a 1590BB with all 6 pots board mounted. The boost switch uses one side of a DPDT footswitch (with the other side being used for LED indication). As usual, set the trimmers to half the supply voltage and then adjust by ear. This would be a good candidate to run off 18v as well. Here's the schematic for reference.
This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.
