Hi. I’m new member , and i would like to say hello. It’s great forum.
I’m looking for help in technical issue about Silhouette HSH with passive DiMarzio pickups an 5 pos switch, which i bought used. There’s some problem with continuity of electical circuit. I checked pots, switch, etc. Do you have some diagrams, photos of original connections? I would be grateful.
