feedback

[cat_eyes_gb]

gah, im still having trouble with my Zoom 707 II. i usually use one of the patches but i usually get this terrible feedback. if i cut down on the dist, i can't get the tone i want. especially when im usng Peavy amps. any tips on the setting of the effects, amp? i use tapping technique almost all the time so i gotta get rid of that awful feedback...
