What kinda music do you play? And you mean 59, right? 69 sounds kinda funny.
I've had a C5 and 59 combo in my LP Studio for a few years, and it was good. I think the 59 can be a bit bassy though. Recently I replaced the 59n with a Jazz to see how it sounds. I don't like the Jazz less than I like the 59. For medium to high gain leads, I think the 59 sounds more fluid. The Jazz isn't as bassy as the 59, but I feel that it's just not as fluid.
