My ds-1 has a really weird sound when i plug it to the amp, is like a strange feedback. Any idea of what is it or what can i do? (I got a really cheap epiphone special II and a cheap fender champion 40)

Turn Down the gain on either the amp or the DS-1.
Stand farther away from the amp.
Don't face the amp.
Could also be the cheap pickups causing the feedback as well.

Just a few possibilities.
