There is mistake in the schematic on B side, 4k7 in the feedback loop of second opamp between pins 6 and 7 should be 47k. When value is 4k7 with volume full you don't have unity with clean and with 47k there is a lot boost like it should be in original.

he guys, does anyone have a schematic of the AC Plus or even a mod? I feel that the pedal is not that transparent and it maybe is because of the mid knob.
any thoughts on how i could bypass that mid knob? :thumbsup

Is It me with issues through mobile or the links have long gone? :shock:
I've got here a bb+ and I could verify the layout above if only the schematic would still be available
