[sdiy] Paia Vocoder clarifier mod toggle?

[Stephen Begin]

I just finished putting together a PAiA vocoder and I think it sounds pretty
rad...maybe the frequency response is skewed but sometimes that kind of
stuff just gives it character...however, added clarity would be nice.  I'm
looking at the mod instructions http://www.paia.com/vocodmod.htm
and I don't really see how I could add the mod as a feature that could be
bypassed by a switch.  Is there such a thing as a single throw 16 pole
switch? Or maybe I'm overlooking a more practical solution?

Thanks
Steve
