Workin' on my first Partscaster, and I have a problem that's probably impossible to diagnose over the Internet, but...here we are! Short version: The pickups I popped into this build sound thin and anemic, with no bass or low midrange. The mysterious part is that this bridge pickup was previously in a different guitar, where it sounded like a proper Tele bridge pickup — spanky and twangy for sure, but with its fair share of low-end growl. I pulled it out of that guitar and put it into my new build and suddenly it sounds like crap! My question: Is there a chance that I've messed up my wiring in such a way that both pickups would suddenly sound thin and weak? Anything else I should be checking out to troubleshoot this problem? Here are the details on what I've installed: - Mojotone Quiet Coil Broadcaster Bridge Pickup - Fralin Noiseless P90 with alnico rods (neck) - 500k pots (Both pickup manufacturers say these pickups do well with 500k pots) - Specifically, I'm using the Mojotone Solderless Telecaster Wiring Harness with 500k pots, because it's my first build, and I thought I might save myself some soldering headaches. - Pickup height looks healthy and normal all around — comparable to the measurements in my Fender Road Worn, which sounds and plays like a dream compared to this new build. Any random diagnostic thoughts would be hugely appreciated!
