so, I'm running a
Nady spc25 condenser mic ---> planet waves xlr F to 1/4 M stereo adapter -----> hosa balanced interconnect cable ---> Ibanez Lf7 pedal ---> hosa 5' instrument cable ----> fender mustang amp (turned opposite from the mic)

but I'm getting lots of screechy feedback, is there any problems that you see with this set up that would give me lots of feedback? Please help, suffering hearing damage

(btdubbs this is in 'recording' thread, because this will soon be my recording setup for vocal parts but I need a solution to this problem first)
