This is NOT a Gibson thing. Gibson does not make a low end guitar, they endorse Epiphone which is a lower end, but if it says Gibson on the headstock it was hand crafted in the USA, and is valuable, especially if it's a real 60's model. My advice is to be very selective about who you take it to, and be prepared to spend a few bucks. Just as a headlight on a Ford Escort may not be too much to replace, a headlight on a Rolls Royce will be very expensive, so with that analogy in mind get a reputable technician from either a Sam Ashe or Guitar Center to help with this, but if this is just a hum, it may just be the amp. A solid state amp will hum when plugged into, where as a tube amp will not. Whatever you do keep in mind that you really have something if you have a Gibson, and any money you put into it will be worth while as an investment, as ALL Gibson's are collectible. This is also not to be confused with the Maestro by Gibson, which is an even lower end than the Epiphone. If this is a genuine 60's model Gibson, treat it with kid gloves, and don't ever get rid of it or trade it without knowing it's current value. Good Luck!
