You can select emulations of different filter types to get a wide range of classic sounds. Crank up the resonance to make it squeal. Flip on the Analog Mode switch and hit it hard to add Dirt, Pump, Shred or Fat. Yep, you can hit it hard coming in and going out, kind of like that old piece of hardware, only no batteries or cables, just great analog sound. (Oh and simulated wood side panels)
The Rhythm Mode gets you moving with the music. Flip the MIDI switch, select 1/4 notes and a sine wave, instant auto wah. To get a little more creative, you can pop open the Rhythm Editor and create a custom pattern that fits your tune. (Save that pattern and use it in PhaseMistress, Tremolator, or EchoBoy). Grab the Groove knob and use swing or shuffle to drop it in the pocket. The only filter that lets you get to your sound and feel fast.
Need more power? Fire up FilterFreak2 (It's part of the package). That's two fat analog filters you can run serial or parallel for total filter dominance. Each can select from Low Pass, High Pass, Band Pass and Band Reject. As well as, 2, 4, 6, or 8 pole filters. Bass, guitar, drums, synths, vocals, anything you want to put through it and anyway you want it.
