I bought an "Epiphone" in the 60's....it was hard to play even when new.......however, I would advise that you call the company in.....where is it???? Kalamazoo Mi?? and advise them of the problem.....See what they suggest.....They have a wealth of information with regards to your guitar.........

For the sake of "convenience"....I once decided to do the (what do they call a "guitar repaiman"...a leitherer...?)..........repair on a Martin guitar that could have been done for free.....and destroyed a really nice guitar..........I still feel like a jerk!!!!
