hey ya'll my name is mark I'm 14 I live in Arkansas and I've been playing for 2 years and I have an epiphone sg and I have a fender deluxe blackout telecaster on layaway at my local guitar shop. Anyway I play metal music and I tune from standard all the way down to drop b sometimes a all the freakin time I mean I go back and forth tuning probley 5 times every day and I kno it wares the crap out of my strings(ernies ball uneven slinky 12-56) I play an 4 hours a day I mean playing guitar is my life but I've been recently reading on the forums here that that will mess up my truss rod and I have never heard that before and I would like to get some information on that so I will kno so when I get that fender off of layaway I will b able to take care of the best I possibly can because it was very expensive. But if u could give me some feedback about this because I would like to learn as much as possible. Mark Troillett
