Mesa Boogie 2:90 voice switching

Post by federico167 » Sun Aug 06, 2017 12:50 pm

Hi everyone, this is my very first post because I have a problem with my 2:90 (I couldn't find a tread about this)

I don't have a triaxis, I use it with anther preamp, so, the voice switching is working strangely... (I have bought the 2:90 some months ago)
When I power it... the 3 voicing leds are on... then.. some minutes later, they start switching off automatically.... If I want to swith tem, I have to use closed plugs connected to the switching imputs.

the question is... anyone have a footswitch schematic around there?

PS: Sorry for my bad english, thanks

You shouldn't necessarily need a schematic, just a simple foot-switch that is open or closed to act like inserting or removing your shorted plug you've been using instead. Most simple footswitches work this way.
