Here’s one you don’t see every day. Unless you’re Neil Young’s guitar tech, and then you see five. This old Conn Strobotuner ST-11 came in with a blown fuse, leaky cap, and busted power switch. When I agreed to take it on I never would have imagined that the hardest part of the project was going to be the switch. Just buy a new one and replace it, right? WRONG! So, so wrong. The switch has multiple stops for the different tuner functions, an extra long shaft to get through the aluminum faceplate, and also serves as the AC mains On/Off. And unless you have the carcass of another Conn tuner to scavenge from you’re out of luck. I eventually tracked down a donor tuner, but even then I had to strip parts from an old Delco radio to make it all work. The upside is that once it was fired up and calibrated it was both SUPER accurate and all kinds of fun to watch spin. If I could fit one on my pedal board, I would.
