I was playing around with my car kit the other day for my portable cd player (yes, I know, i don't have a cd player in my car, just a tape deck.) Anyways...i was wondering what would happen if i plugged the kit into my guitar instead of a cd player? I have an adapter to go from the 1/4" of the guitar to the 1/8" i believe it is of a headphone jack...would I kill my guitar, my speakers..or just create a horrible noise?
