I have an fcb1010 which works very well but there are many who say that you should avoid this machine.
Yes and no.
without changing the eprom, you can do everything the footcontroler does, for 6x less expensive and it remains compatible with all other machines. that alone makes it a must have.
the expression pedal part is "sufficient" and nothing more.
For what?
it does the job without being precise and this is due to the technology used:
The expression pedals are managed by an optical sensor (light) whose light beam depends on the color of the plastic it passes through. On paper, it's good but in reality, if you have dirt on the plastic, the pedal is distorted, moreover, the shade of black is not optimal, the reading of the midi language (0-127) is not precise and therefore you will not hear all the nuances of a wha for example.
now we have to put things into perspective.
You're not selling out stadiums and using another expression pedal won't make your band a world-renowned band.
So if you don't want to spend a fortune, take this fcb1010, it will be great!
For my part, I keep it but it is now replaced by a computer which changes our rigs automatically. So I switched to a “real” expression pedal.
