M4 switching issue

[Sr. Blanco]

Has anyone had problems with the front panel channel switch not switching channels? Mine works about half the time. The midi switching has no issues, just the button on the front. Any ideas? I want to get this fixed as I will be trying to sell this so I can get a dual channel model!

I've never had a problem. Contact Jeff and I'm sure he'll take care of you.

I have never experienced the same problem you have, but I do have another M4 switching problem. With my first M4, all I have to do is send a CC to switch to another slot, which is normal. With my 2nd M4, I have to CC to switch to another slot, and then send another CC to turn off slot 1. It's really annoying, but luckily my Liquid-Foot allows 20 on/off commands with each instant access button. Even though I've found a crappy solution, it just sucks that one of my M4's does it, and the other doesn't.



Sorry to go off track a bit, but maybe it's related..?? Bruce? Jeff?

Alright, I got it fixed. I got some electronics cleaner from radio shack and took the cover off and sprayed it in to the switch. It now works fine. This stuff also worked wonders on the scratchy pots on my little Marshall valvestate amp. It was becoming nearly impossible to get any sound out of it.
