I have the FCB1010 with the UnO chip mod.
I got it from a user here on GFSA, not sure where he got the chip from.
I don't have any experience in controlling an amp with mine, but I use mine to control midi on my PC. I got it working well with Amplitube, and a little bit with Reaper. Couldn't get it to graft with S-Gear 2.
The unit is an absolute nightmare to program, and the only (paid) software I could find that actually worked in mapping the midi is this editor:

None of the freebies worked for me. I would set all the mapping, just wouldn't get any response from the software.
I wish Behringer would update this model and bring something to market that is affordable and doesn't take a degree in astro-physics to operate.
