Problem locating midi fuse .....

stephman said:

Hi there, I can't seem to swtich channels with my new RF3 Midi footswitch on the RM100 head (the lights do change on the FootSW as I hit the buttons but no changes to the amp channels). I've read it could be due to a blown midi fuse.
I've taken the amp apart and found several fuses around the midi board - looking at Petes big fuse locater, which Fuse Number is "the midi fuse"?

Could it be that I'm not prgraming the footswitch properly ?? Should i be hitting the AMp select button first, for 5 seconds and then the Footswitch button for 5 secs ??? What the $#%$# is this system / method ?? Looking at the manual / other posts this should be a simple thing to do ??

Any help / other suggestions would be greatly appreciated.

I'm not sure, most likely closest one to the midi board. Just check them all, take you about 2 minutes with a multimeter.

depress whatever preset you want your footswtich to have on the footswitch, then change the channel on the amp to the one you want assigned to it. Then hold the channel button in for a few seconds.

Thanx for your response - I've now checked the glass type fuses and they're OK. I've also tried the above method for storing presets but still no luck ????
I haven't given up yet, although I'm not sure where to go to now ??? I'm going to struggle to find a tech expert with Randall's midi footswitch in good old OZ......

If all else fails, I may have to install a single button Footswitch to the front AMP channel select button (which works) and go with that ???? So each press of the button will change channels one at a time - that shouldn't be too hard ???

Anyway, if you can think of anything else that would be greatly appreciated.

Steph.
