So I've narrowed it down to the following: Maxon AF-9 EHX QTron+ Barge Grinder Robot Factory Meatwad (currently 1st on my list so far) EBS Wah One The Meatwad is 1st due to size and number of switches and knobs. The EBS is second since I can stick the pedal in one position (prolly fwd for on/offing, and set the sweep to reverse), and set the range. Unfortunately the EBS is also larger compared to most of the others (except maybe the grinder). They all fall w/in the 250-450 dollar range (MSRP, from what little searching I did on MF and such). I'm basically looking for something that I can set on a LPF mode and park the filter at a certain position.
