So I picked up a used Peavey Grind 5 NTB from Craigslist. The bass is in excellent shape, and when I played it initially I didn't notice that it was missing high-end frequencies. (I didn't have another bass for A-B comparison at the time I tried it out.) But later when I had a chance to do a side-by-side comparison, I discovered that the sound is very dark, almost "muffled". It sounds like the tone control is sending a huge portion of the signal to ground. My first thought was a bad potentiometer was allowing too much to pass through the tone capacitor, but I opened up the electronics plate and tested everything with my multimeter. The pots all check out fine, the tone capacitors are sized correctly, everything is properly grounded, the wiring looks pristine, and the pickups register expected DC resistance. After playing with the controls, I can tell that the primary culprit for the deadened sound is the neck pickup. The bridge pickup is low on output overall, but it seems to be a full-range signal at least. But the neck pickup is pretty bad. Just so you can hear what I'm talking about, I did a couple quick recordings. The first clip is a Fender Highway 1 Precision with GHS flats for reference. The second clip is the Peavey's neck pickup.
