In the Spring of 1978,I bought a Gibson RD Artist. The unique thing about it is at the time a company named Norlin owned both Gibson and Moog so they had Moog do some advanced electronics to include active EQ, compressor, expander and preamp circuitry. We are approaching 50 years together. I liked to experiment with electronics going way back and hacked on this one to add additional phase options and other unnecessary features. Through all the hacking and the natural aging process, the poor thing doesn’t play consistently due to end-of-life of the capacitors. Anyway I dove in today and have compiled a parts list on Digikey and will be restoring the electronics over the next few weeks. Here’s some before photos! Wish me luck!
