Ah, I see your point now. The sound of the SP-1 may not be "terribly interesting", but at the same time it cannot be mimicked too easily. For example you cannot do that with a BOSS GE-7 and even not with the PQ-4. Having this special sound (and that of the SG-1) in this strange looking pedal is not the worst thing.
At YouTube my demo videos of the SP-1 and SG-1 regularly receive comments of disappointed viewers. Especially the SG-1 is often regarded as an expensive doorstopper while they say that the SP-1 was a banal EQ. Well, folks, it is not.
