Well, to start with, I purchased it because of its long delay parameters along with the 24-bit technology to use for live guitar, through the amp's effects loop. The overall sound quality is very good.
Now here are my problems with it:
#1.The series/parallel effects parameter is nice, (yet not that noticeable) but why only 2 effects per preset, everyone else allows 4?
#2.When editing I found myself constantly digging out the manual to find out what the 4 letter abbreviations meant, LEDS are cheap, why not use that Behringer thoroughness here?
#3. The layout of knob combinations to alter parameters and that huge scroll knob, I find to simply be a "clusterfudge". A simple number pad would have sufficed nicely. Instant preset access.
#4. What is with the silent delay between preset changes? I need to go from a rhythm preset to a lead preset RIGHT NOW! Not wait for the preset to load!
Overall, I think it's just not user friendly for live performing, good for studio though if you only need 2 effects at a time. This is a classic example of "over-engineering"! OH! And definitely beware of the FCB1010 Midi footpedal problems. Do your homework before you purchase! Thank you. Mike
