Ampeg SVT 2 Pro Footswitch

[Kaiu]

Hey,

I've just bought an Ampeg SVT 2 Pro which has a graphic EQ that can be used as a second channel. This can be done by using a stereo jack plugged into the footswitch socket at the back. Here is what ampeg say:

[i][b]Footswitch: This is a stereo jack which will operate with a standard dual footswitch. The tip of the plug controls the mute operation, the ring controls the graphic eq operation, while the sleeve acts as a common ground to both. With the footswitch inserted, both the front panel and the footswitch mute switches are active. [/b][/i]

However I have a single latching footwitch in the form of this [url="http://www.axess-electronics.com/sc/CFX4-Control-Function-Switcher-p-16136.html"]Axess Electronics Amp Controller[/url]. Is it possible to use a single latching footwitch to only activate the graphic EQ and not the mute function? (I'm guessing not, because putting a jack in automatically turns the mute on)

Or to take two single footwitches (i.e two outputs from the Amp controller) and use this [url="http://www.imuso.co.uk/Accessories/Cables-and-Leads/5025-/5-Meter-High-Quality-Stereo-Jack-To-2-Mono-Jack--Insert-Cable"]Stereo to two Mono Jack[/url], so that they control one of the functions each?

Having to run a dual footswitch to the front of stage would be extremely annoying, as I have all my pedals, wireless etc in a rack. All I have at the front of the stage at the moment is this [url="http://www.axess-electronics.com/sc/MFC5-MIDI-Footcontroller-p-16137.html"]Midi Footwitch[/url] that controls the Amp controller.

Any help would me much appreciated,

Thanks,

Ed

Ed - I've done similar in the past - take a patch lead from the controller and push it in to the footswitch socket in the Ampeg HALF WAY. When you push the socket in usually it will 'click' 3 times. IE , each time the tip passes a contact in the socket. But if you push it in, so it only clicks TWICE the tip of the plug will be in contact with the 'ring' connection of the socket. This contact is the one that controls the graphic. The ground connection will still be touching the correct terminal. It might take a couple of goes to get the plug to click in to the correct position, but in the rack, when it is in place, it should move if knocked. failing that, yes, you will need a stereo to dual mono lead and select the mono connector you require.

I'm using a TC Electronic GForce 2 to change channels on my MXR M80 pedal - however I had to do some very minor customisations to the pedal switching. (Which can be undone and doesnt affect the pedal at all).
