Hey all, I see this problem all over the internet, but I've either tried everything that gets suggested or OPs rarely follow up with helpful solutions. I changed the bridge pickup in my RG470 to a DiMarzio Air Zone. Before installing it, I installed a DiMarzio pickup cover on it using this method (wax on top of cover, then solder base to cover). I got it wired up and it sounds like a single coil: it's not as full sounding as it should be (it's supposed to have a big low end), and the output is comparable to the single coils in the neck and middle position. In fact, the single coils have a lot more low end than the bridge pickup. I've double checked by comparing it to a guitar with a JB in the bridge, and the JB is much, much louder and fuller. Here's what I've done to diagnose: -I've triple checked the wiring/color coding according to the stickies on this forum, and it's all correct. -I've gone over the solder to ensure that there are no cold joints. -I've raised the pickup. The pickup is at a slight angle in the cavity (the poles near the bridge are about 2mm from the strings while the poles close to the middle pickup are about 4mm). -I've replaced the switch with a new DiMarzio switch. -I've checked the resistance on the pickup. It reads 17kΩ with the switch in the bridge position (which is normal, according to DiMarzio's specs) and about 3.6kΩ when split with the middle single coil, which is about 6kΩ on its own. I assume this is roughly correct due to Ohm's law, but someone may need to correct me on this. Other than that, I'm not sure what else to do. I'm hoping I didn't fry the pickup by installing the cover, and I'm not sure that the slight angle would make such a substantial difference in the sound. Any suggestions are welcome!
