Roland GP-100 Problem

[rockmaster1964]

I have a Roland GP-100 that is having some sort of volume level problem. I have a Rockmaster preamp running in effects loop 1 and a ADA ampulator running in effects loop 2.

 

When I first turn on the GP-100 the distortion is weak and the volume is lower than it should be. If I turn the GP-100 off and then back on everything is okay.

 

Also from time to time I will have the volume level drop down own its own.

 

Anyone have any idea what could be wrong?

Easiest thing to do is clean all the jacks with Deoxit. Beyond that it's a crap shoot.

Are you sure it's the GP-100? The Rock master efx loops are notorious for a weak sound when the contacts are dirty. If you don't have cleaner handy, plug some jumper cables in the 5 loops of the RM.

I have nothing in the rockmaster effect loops and it only requires rebooting the GP-100 to get things going again.

I'm just suggesting to make sure it's not the RM efx loops, which have failed on me numerous times.

Next time you get a weak sound, plug a jumper cable in the 'common' efx loop and the efx loop of the channel you are using. If you're on one of the OD channels, remember there's a 'crunch/ultra' loop send also.

It could be a cable problem too.

Diagnosing a problem is a process of elimination.

Okay, thanks for the suggestion.
