I just got this pedal a week ago, and I completely fell in love with it!
Normally, i'm not that big a funk bass player, but since I've got this pedal, I discovered grooves I didn't know I had...
Build quality is A++. Very sturdy pedal, throw it at someone's head, and the damage will be considerable (to the person's head at least..) ;-)
Sound is A+. the possibilities with the intensity and range are legio. You really can get any sound you want out of it. The only thing that annoys me sometimes is the whooshing sound when your filter drops down after a sustained note. This is however removable by the intensity knob.
Price-wise, I don't think you can get a better bass envelope filter at this price anywhere!
decent packaging, good price, great build quality, and an awesome sound.
All in all, a must-have if you're planning to buy a decent effect pedal for your bass!!
