I was talking to a guy recently who said he HATEs tap-tempo. Reason being that in a band context, unless you are playing to a click, there's little chance that the band will maintain that same tempo after you tap it in. I haven't actually seen anyone trying to keep their tempo locked onstage. I figure there's more going on there.
I saw the Mermen (local surf/psychedelic band) on Friday night and there are a few places where the guitar player opens a tune with a LOT of delay, but those tend to be spacy type intros where the band isn't really kicked in. It's just a trio and the drummer is mostly doing flourishes at this point. I think the guitarist was using a tape delay and I have no reason to believe he's tapping tempos in.
But it made me think that there might be some use in having a couple of extra settings for any tap tempo pedal.
e.g. # beers consumed. this would contribute to a sinusoidal tempo fluctuation combined with an overall tendency to slow down.
Back in the day, there were some nasal powders that would cause a general tendency to speed up. But I don't want to promote that sort of behavior, so I won't talk about it any more.
