Below are pictures of the repair and restoration of a Gibson ES 335 guitar. The guitar had intermittent electrical problems, action, intonation and tuning problems. The finish was dirty, dull, and had scratches and imprinted damage due to stickers. Plus, the hardware had finish deterioration and corrosion. The guitars as-is condition necessitated a complete tear-down for a proper repair and restoration.
The before pictures show the ES 335 Gibson in as-is condition with dirt, corrosion, flat frets and finish damage before tear down.
Note: Unfortunately, I got too involved with the repair/restoration of this Gibson ES 335 and forgot to take 'During' pictures. The guitar was completely disassembled, including pulling the wiring harness.
Chemically cleaning internal electrical pots, switches, jacks, etc. would leave a harmful residue on the inside of a "F" hole type electric guitar - in addition to those parts being hard to reach for proper service/cleaning. Thus, the best method is to remove the wiring harness for proper service/cleaning.
All parts were cleaned polished, metal parts were oil teared and the finish was wet sanded/polished, frets were topped and polished, the Gibson received a final set-up and intonation adjustments.
These photos show the restored Gibson ES 335. The guitar has original pick-ups, etc. and is now in excellent+ condition and good for many more years of playing. I'm thinking - Johnny B. Goode, Mabellene and Roller Over, Beethoven. Maybe a little Keith Richards and the Rolling Stones.
