Hi!
Is your amp the recent "multi-watt" recto? I think it doesn't have a direct MIDI-connector. The footswitch connector is a DIN-jack, though it looks like MIDI-connector.
There are many switcher-boxes on the market that convert midi switching to jack switching. For example
RJM Mini Amp Gizmo: http://www.rjmmusic.com/miniampgizmo.php
So, you could connect your regular midi footswitch to Eclipse MIDI IN…. and Eclipse MIDI OUT or THRU to that sort of switcher box. Then it would send the switching commands to amplifier in "analog way", via jacks.
Here is a site that might help you with getting the picture of those switchers…
