I feel like a super noob with this one but I just got a new g&l comanche semi-hollow and I can't get over how amazing it is! However I just broke a string after a couple weeks and I am not familiar with the stringing process with tuners like these. They are the ones where each peg has a circular screw and I'm not sure what it is loosening or tightening. Also it appears that each string is only wrapped once, so their is no coil like my other guitars. For the life of me I can't find any videos about on how to re string a comanche, or any videos demonstrating the PTB system and/or even a diagram of which pickups are selected...Anyway help would be appreciated, the pic below is the exact guitar I am using, thanks in advance!
