OK, I was walking through the kitchen with my guitar on with the strap and the strap popped off! Apparently my hand didn't have a good grip on it cause the guitar fell and hit the floor! There was no visible damage but I've since noticed that when I put it through the amp, no matter whether I turn Reverb all the way up or all the way down it reverbs and at the same level. Could this have something to do with the drop or is there something wrong withy amp?

The guitar is an OLP MM1
The amp is a Crate GX-30M.
