Ashdown 4-way footswitch issues

Hey there,

I recently got hold of a fabulous used Ashdown ABM500 Evo III head and 4 x 10 ABM cab on eBay. I love the tone from it and especially the switchable features - valve, EQ, compression and sub-octave. I wanted to remotely control these features so I bought an Ashdown FS-4 to do so. However, when I plug it in, it lights up and turns on the sub-octave effect permanently - also using the 4 switches does nothing.

Is there maybe an FS-4 specifically for my amp and I have the wrong one? Has anyone else had this problem? I did notice one other similar post regarding an FS-2 but there wasn't a solution presented.

Any help would be great! The web seems a little thin on Ashdown footswitch stuff.

Cheers,
Russ

 

Hey, thanks for replying. Tried this. Still the same. I guess something is broken... I'll have the amp footswitch socket checked out.
