I've owned them all - Roland, Hammond, Fatar, Crumar... - and I agree with Ian (OMG!) that bass pedal use in the USA is sparse. I sold my last set of Crumar's only because auto-bass does a decent enough job. If I really need a dedicated bass line, then I do that on left hand with auto-accompany off. Of all the units I've had though, I feel the Roland has the best MIDI pedals available. I also liked my old Crumar self-contained analog sets, but would opt for Roland PK5 if I needed another.

To answer Donny's comment - I bought my last set of pedals to go with my Hammond XK-1, but soon set them aside.
