a couple days ago at practice i was messing around with my smallstone and hitting some heavy stuff on the low b, didnt have the head cranked up, but it was pretty loud still... anyway, after i stopped i noticed a slight whine sound coming from my amp, barely noticable, but definately there. I turned the power off and on, still there, switched cables still there. etc etc. finally i unplugged the small stone and it was gone....did i possibly damage the pedal? i cant imagine how i would have, but anyone know anything that might have happened?
