Ive had good and bad experiences at GC. Been going to them since the 70's. When I lived in the Bay Area, I went to All 3-4 in the area, and had pretty good luck. Then, about 6 years ago, I bought a 5'er that had a P-J setup that sucked, so I went to GC Medford, OR. and told the salesman what I had, and that I wanted to get an EMG setup for it. He sold me a P-J setup, and I went home to install it. B string just never sounded very good and i was dissapointed. Then I found out that he had sold me a P-J setup for a 4 string-not for the 5. I went back and complained, but of course that salesman didnt work there anymore and I was screwed. Still havent been able to afford a pj5 set. A couple years later, They had a Christmas sale with 18mo no interest, no payments. So I bought a few things.
Well, the salesman entered it in wrong, so the company that does their financing didnt know I was on the no payment plan and kept sending me bills-which I ignored knowing I didnt have to pay for a while. Well, that screwed up my credit. When I finally became aware of the problem in April, I went back repeatedly and talked to the original salesperson, the manager, and anyone else I could get ahold of and each time they got on the computer, told me what the problem was, and hit a few buttons and said it was fixed-it wasnt.
Finally, they got a new manager who took care of it immediatley, (Jonathan ROCKS!!) and he has taken VERY good care of me since.
I have noticed that the prices are getting out of hand, and I have been making most of my big purchaces on ebay, but for strings and things they are convenient.
