1977 Gibson / MOOG RD artist electronics with the schematics, A lot of players loved the Artist guitar , but at that time, the expander/compessor and active electronics was a new thing.. A lot of players would take out the electronics & put in regular Humbuckers & wiring, something they were used to. This is how I got this circuit board from the 70's. Unfortunate that I do not have the pickups.. After years have gone by, active electronics are normal now. The RD Artist had a great sound & now there might be a few around that the player may want to put back to stock...And they do not have this part or there's one that needs a spare circuit board with all the electronics and here's one!!
