Yamaha CS80

hi folks-im wondering if anyone has experienced this? my cs80 will randomly get a distortion on the output, and it will then randomly go away. it will never last longer than 5-7 seconds at a time, and it doesnt seem to be "control induced" in any way. (it sounds alot like a preamp does with the gain all the way up(signal still comes through). im going to be recording with it in a little while, so i kinda would like to clear this up. any leads on this?

also, i have heard a horror story(old crow site maybe?) about shorting things out by plugging in an expression pedal. i have yet to do this on my 80. any advice? plug it in before i turn it on? should i be worried, or no? 

thanks guys!!!

Hi RJ,

Could be a cap with a dry joint on the PRA board. Or a dry joint on 
one of the wires leading into the PRA board.

The pedel should be plugged in while the 80 is off. And don't plug 
it into the wrong socket as this will blow the 15V track clean off 
the back of the PRA board.

Hope this helps ya!

you "have" to use a CS80 expression pedal...There is a light and photo
cell inside the pedal....it is not a pot...If anything is shorting
inside the 1/4 inch TRS jack, you will send voltage down the ground
rail and end up needing service.....

Could it be a dirty output-hi/low-switch on the back? Just mess 
around with it and see if it cuases the problem.
