I just had a few moments with the newest offering from Source Audio, the Manta bass filter. Absolutely amazing. I thought it might be good to have a central location for sharing settings and demo sounds without clogging up the S.A.S.S. If you haven't heard about the Manta, it is a dramatic upgrade of the Bass Envelope Filter Pro. All of the best features of the BEF are available plus a whole lot more. To my knowledge, this is the only filter pedal with built in drive. This goes beyond anything I have tried before including great pedals like the Xerograph and Wonderlove. Here is more info on the Manta: http://www.sourceaudio.net/products/soundblox2/manta_bass_filter.php I have no affiliation with Source Audio, just an avid fan.
