My basses all feedback when fuzzes are on and I'm not playing a note.
With fuzz pedals I often find that crunchier settings are found towards the low end of the "fuzz/drive/sustain" knob.
yeah well, I use an svt II preamp set pretty dirty, I use a nobel odr-1 overdrive for addtional dirt and I want the fuzz to Sound like the world is coming to an end, really kinda "broken" tone where the notes break apart. with Settings like These my thunderbucker equipped bird works a hundred times better than the casady.... the casady is up for sale (Germany only) as I use the P in one and the bird in the other band now..... and yes my "mexican bumper" works great for punkish hard rock like I do.
