It's got knobs for input vol, peak (resonance), up/down (blends the two I guess), band-pass/low-pass (blends), and output vol. The input vol is nice because you can crank it and get a little bit of grit before the filter.
I've used this pedal with 4-string bass, 8-string bass (great for noise by the way), samples, and in a feedback loop. It's great on both basses, really good on samples, and ok in a feedback loop. I actually don't have a lot of experience with feedback loops, but this spits out some synthy tones and responds well to tweaking, so I think that's good.
The range of the filter is VERY extensive. The lows get super low, which is nice. As with most envelope filters (or filters in general I guess), the more frequencies you put through it, the funner it is. That's why I really like 8-string into mixer, FX send into distortion into the Ashdown filter into a return channel, and then that feed back into the FX send. Feeback from the mixer, and from the Amp to the bass. I tweak the EQ on the 8-string, and the filter and get lots of crazy sweeps and stuff.
This isn't as versatile as the Boss AW-3, but The sound is better, it can get way lower and move way faster, and it offers more control.
Good Points: Extreme range of frequencies
Input and output volume control
Sturdy
Inexpensive
True-bypass
Light-up VU meter is sexy
Bad Points: Big
Only OK in a standard feedback loop.
