honestly, warlocks are horrible guitars. terrible sound, and as im sure youve noticed, they fail miserably over time. i reccomend any fender strat or gibson les paul obv
however, if you are hell-bent on keeping the warlock, check the truss rod. You can also take it to your local music shop and have them run tests on the electronics. most likely what it is are the pickups, or your bridge. warlocks are made of cheaper materials, and wood expands and contracts when it comes into contact with varietal weather patterns. at any rate, save some money and buy a quality guitar
