A superb effect

She's a beauty alright! A tiny package with all the parameters you want, built like a tank! The envelope follower circuit is is extremely responsive. Great for funky stuff of course, but I've found other great uses. Run it through a volume pedal to fade in the attack and you have yourself a great sounding polyphonic synth! The only thing to be aware of is the the possibility of overly resonant peaks overloading the inputs of subsequent gear in your chain. The sweep has the capacity to go very low, and the Q can get pretty sharp, so use responsibly!
All in all; a very reasonably priced beast of a little module to ad to the arsenal.

Fantastic pedal

I checked out every bass envelope filter currently in production. This one was by far my favorite. Versatile effect, with control knobs for every parameter. To me it just sounds so much thicker than any other EF, and I'm loving how small it is. I use a cutting board for my effects and space is definitely a factor. No on-board distortion but it works extremely well with my Bass Big Muff, which is a much better distortion than that of any other envelope filter which has one built in. It's not very heavy, but it seems to be very durable. I use this in the effects loop of my Tonebone Bassbone bass preamp, into a Peavey VB-2 all-tube head stacked on two Ashdown cabs, a 210 and a 115.

Great tones for funky grooves!

Having used many different envelope filters over the years, I was skeptical that I could find a modern product that would hold up to the older pedals that I have lost or worn out over the years. This pedal is not only chock full of fantastic tone, but it is also very durable. I highly recomend this pedal.
