Hi , I have just got a vintage Gibson humbucker to fit into my Epiphone Rivoli and some help would be well appreciated. There appears to be just one connection, a single wire, should I just solder that directly to the wire connected to the old one? I was under the impression there would be two connections but It doesn't look like that now. Also does anyone have any tips for improving anything before I fit the pick-up? I red somewhere shielding the pick-up area with foil can improve the amount of noise coming off this bass, any thoughts on that? Cheers and thanks for any responses in advance.
