I like it here. People are helpful. And... here's the best part, this is the only guitar store that provides guitar picks for testers (that I've seen). Even though I always have a pick holder in my keychain, that's a great touch because most people are normal and don't carry picks with them.
I've sold used gear here and got literal ca$h which is great. The formula they use seems fair, they'll pay you maybe 50-70% (depending on condition) of what they intend to sell it for, so do your research on the selling prices. You'll get a 10% discount on non-used, non-sale items if they end up buying your used gear.
