I just got finished with the install of EMG pickups in my Peavey Grind NTB 6. I went with the 40-P and the 40-J models. The install was pretty easy, except I couldn't find any wiring diagrams that explaned how to hook up 2 volumes and 2 tone pots. I finally figured it out. The instructions EMG sent showed 2 volumes 1 tone, or 1 volume 1 tone. All the diagrams I dug up on the net showed the same configurations, I guess 2 volumes 2 tones is a rare thing? Here is a link to the sound clip. In the clip; the 1st 30 seconds is the bass with the stock passive pickups, and the last part is the new EMGs. Both were recorded with both volumes at 100% and the Tone pots in the middle (or 50%). Also, I put new Elixers on the bass, when I changed the pickups. edit: Oh yeah, the bass is running direct into my PC.
