Just finished up this mid 1960's Gibson GA-15 RVT Explorer amp for a good friend. Installed power tubes, a new Mojotone capacitor, and a grounded three prong power cord to get it back up and running. You don't see these amps everyday!

I don't normally take in much guitar repair, but I was glad to lay hands on this sweet 1985 Gibson Les Paul. Came by to have all new quality Faber brand aged nickel hardware installed, a set of real deal vintage Grover tuners to match, and set the intonation. It's a sweet one for sure!!

A good friend brought this 1950s Electro Voice SP15 from an old Crosley tube record player for me to resurrect. After a little retrofitting of an EV 15L kit and a new aluminum dust cap to help retain the high end treble response, this speaker should be good for another 70 years of service!

The 1977 Peavey Mace 320T that got an overhaul for a good friend! New matched full set of 6L6GC Ruby Tubes, new Mod capacitors, and a few resistors and this thing is back to the stage! This is the same exact model famously used by Lynyrd Skynyrd. A real piece of music history preserved!
