As far as GC, it depends. Guess Im blessed to have some cats at the GC I go to that know what theyre doing (one is a studio bassist that tours alot). I usually do it myself, but I thought I might take it there to see how they do. I only deal with two guys there and they always take care of me so I thought what the heck. He did a great job I must say. Lower than Ive ever had it.
