So I'm thinking about treating myself to a new guitar within the next two weeks and I have one last qualm. The tremolo. Im a heavy trem abuser, and I need one that can last. Ive been looking at and trying some of the new Ibanez prestiges and the edge zero two with ZPS seems to be made out of a soft cheap metal alloy. is this true? Ive seen other comments that the hardware corrodes and rusts out without weeks. also I have looked at ESP, the Horizon FR-7 model. and the Ibanez 7 string Jem. I like the benefits of the ZPS so thatd be my first choice, but im not dropping 2k on a guitar that ill be replacing the trem in soon. can anyone offer insight? help is appreciated!
