There are no sustain pedals on Hammond organs, and I don't think too many organists or accordionists use one, and, the arranger is basically a single keyboard home organ, or, perhaps, much like a horizontal electronic accordion.

The arrangers have had velocity sensitive keyboards for quite some time now, so a volume pedal isn't really a necessity.

Having said that, I never play an arranger without my trusty sustain pedal, and I use a volume pedal quite a bit too, but everyone is different, and I've met several people, some who were pros, that did not use either.
