I recently picked up a used Schecter Revenger 7, and it seems like it goes out of tune a little faster than my other axe (Hellraiser C7). I swapped out the pickups and had it professionally set up by the same guy who does my other guitars, so I don't think it's how they're strung or anything like that. What are some things I can check to diagnose the issue?
Basically I'm wondering if picking up a set of locking tuners would help, or if maybe I need a new nut or something. How would I go about determining which? Also, I'm not really seeing much in the way of tuner sets for 7 strings, so I'm assuming I'd have to call up sperzel or gotoh and custom order them?
Nut probably doesnt need to be replaced, but needs to be filed. Im surprised the tech didnt do that with the setup honestly. The tuners should be fine on that guitar unless something happened to them. take some excess length of the same gauge string and see how freely it glides through the slots.
