Actually, one dumb questions, and one maybe not so dumb question. Bartolini sells "complete electronic Harnesses" wired with pots, and a push/pull active/passive switch. THe one I need is the HR-4.5AP/918. Does anybody have any experience with the harness? How easy are they to put in? Do you just gut your existing system and drop it in? The second question is, what is the difference in sound between the "deep" tone pickups and the "bright" tone pickup. I want a sound that is stingray like, which I think of as deep, but with a lot of edge to it. so which should I get? Bright? Deep? One of Each? I was thinking about putting the Bright pickup in the bridge position, and the Deep one in the Neck. Or am I thinking backwards?
