Hey all, I need some advice. Even though I owned an L2500 years ago, I'm kinda new to the G&L family. I just bought a used 2002, L2500 on the bay. Bass is in cosmetically amazing condition (burst). Bass came yesterday. I did a set up and played it with the dead DR Low Riders it came with and there wasn't a problem. I restrung the bass with Elixir Nanowebs and didn't string through body but rather through the bridge. I plugged the bass in and HUM city. Really loud hum that would get me fired on a gig. I love the tone of the bass but can't deal with hum. I'm getting the hum in all settings: parallel or series, all pickup combinations, it's pretty horrible. The seller says that he'll give me my money back or will give me $350 to fully gut the bass and replace everything. What should I do? How do you guys deal with the hum without rewiring and losing bottom?
