I was playing my Foundation just now. Whenever I play hard and dig in or slap, the signal distorts. I lowered the pickups and VOILA, gone ! Sounds perfect now. I need to turn the volume up a hair, but it's clear now. So, if any of you have the same issue and think it's a problem with the pickups or something, it may just be the pup height. BTW, I LOVE how simple it is to raise and lower Super Ferrites. Why can't ALL basses be this simple ? Peavey and Alembic got it right.
