they don't really have a rating system that they follow. i did a sit down at a GC with what turned out to be the guy in charge of trying to improve the used listings. the poor, small pics, the claims of banged up stuff being listed in excellent condition - he's been trying to change all that with no luck at all. he said it's up to the managers how to list used stuff, and most would simply like to list it with as little effort as possible.
but for us, that's where their return policy comes in. it's worth a shot.
yeah, but consider this thread. there's probably no real issue, yet it's a thread with a title warning us about GC. all the OP had to do was call GC. most times, they'd have either refunded him part of his money or sent him an RMA. instead he started a negative thread. and that's the case in a lot of threads.
i don't think i've ever had a bad experience from GC, and i've been shopping with them since 1972. it helps that my expectations are realistic - many of the guys at GC get paid very poor wages, and a couple i know at one store only work there because they can get time off when their bands tour, then come back to their jobs. many don't get commissions and some are clueless. that's okay - i can do my own research, believe my own experiences, and have had GC and sam ash take multiple returns quickly and easily.
i HAVE, however, had a bad experience with sweetwater and wouldn't shop there for several years as they didn't take care of me even afterward. my relationship with sweetwater has improved - i love knowing the weights of basses i buy. but GC has never done me wrong. no company is perfect, but for me, how they deal with me when there's a problem is a big part of what makes me come back to any business over and over.
btw, between my husband and i, we have well over 200 purchases at GC.
