smalaney Posted March 12, 2012 Report Share Posted March 12, 2012 Last May (2011) I purchased a 1960's Custom Shop Les Paul from Guitar Center. After fixing some obvious problems (tubes, loose wires) on my new Fender amp, it became quite clear to me that the "hum" at medium to high volumes was coming from the guitar. The local Gibson repair center noted a few things. 1) No shielding on the either of the body cavities 2) Ground wiring incorrect 3) Non-standard pots (no Gibson name on the back of the pots) 4) Different impedance between the Bridge and Neck pickups. I took my 1964 vintage Musicman guitar (with built in pre-amp - shielded body cavity) hooked it to the same amp, no "hum. Now it has been a number of years since I got my electrical engineering degree, but as hi-gain preamps on guitar amps have come to predominate the scene, shielding the electronics in the guitar is done specifically to cure this kind of (hum) problem. Gibson guitars previous actually had metal casing around the pots, etc specifically to eliminate these kinds of problems. I have contacted Guitar Center, but wonder is anyone else seeing these kinds of "quality issues with the guitars they buy from Gibson. I have always wanted a very nice, playable Les Paul, and after saving up for it (and numerous arguments with my wife about spending so much money on a guitar) I feel cheated. The guitar is still under warrantee, and it looks like the service center will try to get me a new set of pickups, but frankly, I would be hard pressed to recommend this (or any other Gibson Guitar) to anyone I know. smalaney Link to comment Share on other sites More sharing options...
