TB has a much better selection than GC.
I agree with that.
So when/if I sell a bass on here, I know it's history and I impart this on the buyer as a value added item.
I hear you but the problem (maybe just for me) is that I don't know you so my faith in your word is based only on your feedback, pictures and description. It's tough to compete with GC where I can take my sweet time checking things out and return it without any hassle if I feel the need. And believe me I'd much rather spread money around TB than GC.
