I just finished up my HSS BMP-1 project and I'm having an issue I cant get sorted..so here is the gratutitous guitar pic
Its loaded with a ProTrack/EMG-SA/Fred combo, the passives are running through the BMP-1 and out to the 5 way, the EMG is running directly to the 5-way middle. The output from the switch is run back through the BMP-1 volume control. Theres a 25K push/pull tone which splits the neck and bridge as well.
The pickups each work individually, with the BMP-1 volume levels significantly louder than the EMG-SA which I expected. My issue is with the 2 and 4 positions : instead of getting a nice in-between tone of parallel EMG/BMP-1 its as if the middle pup isn't even on i.e. position 1+2 sound identical (all neck) and as are 4+5 (all bridge). I've checked the 5-way and its operating as expected, and the pups all work as expected individually. Even with the pups split there is no mix tone with the EMG.
I'm stumped....any ideas?
