"Liquid-Gooey-Q-Tron with funky warts on the side"
Overall: 4.5 out of 5 stars

Sounds Very Funky! However it took a while to find the "Right Sound" as this pedal is very sensitive. Patience will be rewarded. At the moment it is the only effect that I am using. Keep in mind that no two envelope filters are created alike. For instance, the sound I get out of the QTron is worlds away from what I get out of my Mutron III+, another excellent effect.
4 knobs and 2 switches to toggle to your heart's content. For those of us with active electronics this is a must as the Qtron is very sensitive to our electronics.
Ease of Use
...Again, patience. You're not going to take it out of the box, plug in, and sound immediately like Bootsy. Take your time.
Well, it is somewhat rigid, however I would want to drop it either. It's certainly not built like an MXR pedal which is what I would assign a 10.
I bought mine used for a fraction of the cost. It could/should be a bit cheaper...
Manufacturer Support
Nope. Not yet at least.
The Wow Factor
Not the best filter on the market - but close. I like it and I don't anticipate selling it and shelving it.
