Recently I change IC on my faulty MIT 1994 DS-1. I changed the original IC Rohm BA728N (SIP8) to NJM2904 (DIP8) using SIP8 to DIP8 that i make my self. The problem is tone knob become level and level knob become tone. LED always light even in off position (dim). Sorry for my english. Thanks
Thank you Dr Bob. I'm from southern Malaysia. I'm newbies in electronics. Since lots of electronics component manufacter have their factory here, so most of the components are very cheap. I wanna try before order some online. But I just can't find SIP8 opamp chip. Local shop here are not supportive for guitar diy or efx diy. I tried every opamp chip I've got but still the same result. I'll try post some pic or maybe videos next time.
