I have a Fender Hot Rod Deluxe and lately have been having some problems....

This amp has 2 'channels' When the first one is selected the indicator light if off - which is normal. If I switch it to the second channel the light turns red (or yellow) - this is the channel that has the spring reverb on it which is sooo fun. Anyway lately when I'm playing thru that second channel, the amp will "drop" out of it and go into the first channel with the clean sound and no reverb. When this happens the light goes from red (or yellow) to off as well as the sound. Sometimes it will go back to the 2nd channel if I give the amp a little nudge or rock it a little. The other night it seemed to be playing fine and then we moved it a few feet and it started doing it again.

So if anyone has any suggestions/ideas it would be greatly appreciated!!!

Thanks
