Hi everybody,

I have a Fender 1000 Roc Pro with a big problem. When I'm playing it, sometimes (quite often) the sound cuts off and the LEDs of the Gain Select start to blink. The sound comes again by itself or when I hit the head (softly). I think there must be a bad contact or a broken track, because it seems that the vibration of the speaker causes this issue.

It all started about a year ago, I looked the board of the amp and I saw that the R173 had a broken contact. I fixed it, but after a few months, it started again to cut the sound. I've checked with the tester all the contacts, but I can't find anything.

Do you have any idea of what or where could be the problem? Also, this problem with the sound happens more often when the amplifier has been in a cold ambient.

Thanks a lot.

From what you say I would pull the board and double check all the solder joints with a magnifying glass . Some guys like to resolder the whole board. Fender had some bad solder joints on their SSamps
