I bought a used mid 70's ibanez les paul junior copy a few months back for about 400 bucks. I have done the following to it to make it playable etc: -all new electronics.. everything -all new hardware.. everything -new frets -new nut basically the only original parts are the wooden ones... Anyway this guitar will not stay in tune for anything! It sounds amazing but as I play it I find that I am literally tuning the damn thing every couple of minutes... it is driving me f*cking crazy. Is there a chance that this thing is just a dud... Is there anything that I can do? is there a chance that the nut just needs some lube? I havent tried that yet.
