snitter Posted January 19, 2014 Share Posted January 19, 2014 Im getting strange volume fluctuations from my amp. When i turn it on, there is sometimes no sound until i change patch on my fbv shortboard. Halfway through a song, the volume can drop dramatically. If i change preset and go back to the original, the sound comes back. Any ideas? The amp is just over a year old (typical-just out of warranty!) thanks Quote Link to comment Share on other sites More sharing options...
fflbrgst Posted January 20, 2014 Share Posted January 20, 2014 Possibly loose knob problem - vibrations when you play 'waking' the channel volume knob. Couple of things you can try - easy one is to put the channel volume to '0' first, then select your patch. A rubber oring placed under the knob will make it less apt to turn from vibrations. If its not that, you might need to do a factory reset (hold the A button in while turning on the amp) but make sure you back up all your user patches with Spider Edit first.
