I have lots of arranger clients that do not use a sustain pedal.

When you think of it, it is really only designed to use with piano sounds, although some of us use it to good advantage with other sounds.

I can easily think of three pro arranger players I know, that don't use a pedal.

Many players come to the arranger after being trained on another instrument that does not use a sustain pedal...lots of guitar players, as well as organists, and accordion players.

I find it handy, but that doesn't mean that everyone else should.
