Just build a 15/6/1 fearful. Using the peavey 3 way crossover recomended in the fearful wiki Getting a strange quite "fuzz" sound when i play some notes sometimes.. Pretty sure its coming out of the 15 driver. Sometimes when I play certain notes if i let them ring out there is a quite fuzzy electronic tone that can be heard as the note fades out, but other times its not there. I'm thinking it could be the crossover or the power amp? tried 2 different preamps through my P.A. ; same intermitten weird fuzz sound. I'm gonna try through a totally different amp on Wednesday, if that doesn't fix it I guess its def. the crossover. anyone come across this before? I'll post some sound clips after I try out the cab /w the different amp.
