... modyfiny the Boss SD1 for the Ibanez 808 tone. I remember getting this diagram years ago when i was a member of the Guitar.com forum, but i totally forgot about it. Just wondering if anyone has done it?
I want to do this, I don't have a SD-1 though. But I would also include a better op amp chip. The JRC is supposed to be the original but I would go with a better one like the opa213pa.
