My cousin works over in Detroit as an architect, and has bought at the same Guitar Center for the past 10 or 15 years. They absolutely love him, since he spends an hour there every day after work. He's bought 3 guitars there in the last 6 months or so, and constantly getting killer deals. And when he buys a guitar there, not only do they bend over backwards to lower the price, they shower him with strings, cords, picks, straps the works.
Now if I could get the same service when I was there.
I get like that at the local(ish) one in Toledo, OH, being the lead guitarist in the biggest local band.
But I still won't buy any "new" guitars there. If I'm gonna get a new guitar, it better have only been played by me and tested by the guys at the factory.
I can't stand when these kids or these "musicians" who work at GC mess with the stuff, like trying to tune a Floyd Rose without using the Fine-tuners and whatnot.
Of course, sometimes their lack of knowledge and adherence to protocol comes in handy, though, like when I got my RG2027 three years ago. I assume it was priced the way it was because of all the damage to it, but it was all only cosmetic damage to the finish. which was easily fixed, and any decent musician would have know the same. I purchased it used...
It was almost impossible to not laugh maniacally as I paid for it.
As I was saying, I'll only buy Used gear there, as the new stuff they have is all the same, and there's no variety to it.
