as i say, it's controllable to a certain extent, but ideally, i'd like a wee bit more volume, but that would be the straw that breaks the camel's back. i'm on the very edge of controllable feedback, any more gain or volume would render it constant. it's not so much the screaming, squealing kind that i had with the stock pups, more of a wail. don't get me wrong, i adore harmonic feedback, and often use it, but this seems to be semi-harmonic feedback that is provoked by microphonic. as soon as i stop playing, it screams instantly.
another thing, i just found out that the pups are self-contained and don't require a cover. should i take off my old pup covers? the holes in the cover are too small and cover part of the poles anyway, and maybe removing these will help - one less thing to vibrate, after all. how easy is it to take covers off? (i had my pups installed at the shop, you see).
