Based on your description, I would be looking for a clone of a Tone Bender MK2. They work well with buckers, sit in a band mix much better than a muff or fuzz face, and still get raucous without going over the top.
I was thinking the same, but IIRC HIAR already had a ThroBak years ago, which I think is a damn good bender.
EDIT-I should really read the thread all the way through before responding.
