Hello, I have an issue with my 2266 footswitch. It was being intermittent and not always working, both the dynamic range and reverb switches.
I figured out that the cable had become damaged near where it enters the chassis, so I re-cut, stripped and soldered the wires back to the switches. Reverb works perfectly now but for some reason I have to press the DR switch twice each time to switch the amp.

So, I replaced both switchs, but the problem is the same. I feel pretty certain I've wired it correctly, its very simple and I took before photos for reference. So its making me wonder if the amp has a problem too?

Has anyone else experienced an issue like this?

Sounds like you wired it up incorrectly.
IIRC The issue is that the DR requires a latching switch and Reverb a momentary switch.
So I would recommend to swap wires and then recheck...

Both switches now installed are latching, but only the reverb works. So it seems weird to swap the verb switch for a momentary one. But i'll order a momentary switch and test anyway.

Cheers

I've been thinking about this, and tell me if i'm off course here but...

If the DR circuit is currently switching when I press the switch twice, that would mean that the circuit is switching on the 'rising edge' of a signal being engaged. So turning on the signal switches the signal both ways, alternately, rather than on/off being for either setting respectively? This would make sense then that the DR switch is the one that should be momentary? That way every actuation would make the signal come on, thus switching the circuit.

Thats gotta be right, right?

Edit - I've just found an old post by Steve Dawson and I am correct. You still technically solved my issue though so many thanks spanngitter.:applause:
