A coworker who doesn't play guitar scored this old Magnatone lap steel at a yard sale and brought it in for me to check out. He then asked if I'd be interested in buying it at a price that's a profit for him but seemed reasonable to me. I brought it home for the weekend to find out if it actually works - it does, and that old pickup sounds pretty good through my Twanged Valve Jr. Volume and tone controls work. Condition is generally good, with some scrapes mostly in the picking area and a few dents/bubbles in the metal "fretboard". The triplex chord-changing bridge is interesting but needs some TLC - seems it should be disassembled, then cleaned up and lubed before reassembly. Haven't figured out how to tune it yet; the strings appear to be wrapped around the Allen screws visible in the nut assembly. I told him I'd bring $100 cash for it if it worked... do you think it's worth it? Information on how to tune it (no keys) and how the bridge works would also be appreciated. Thanks.
