So I got a question about experiences with it over in the PYPB thread, figured I'd copy it over here:
I like it and it works very well with bass thus far, though I'll admit I need to spend more time with it. They packed a LOT in a very small box, and there are certainly areas I haven't explored very well yet. I was able to quickly dial in sounds I liked for flanger, phaser and chorus (there is even a bass chorus mode build it). The other "traditional" modulations sound good, though I don't have a great frame of reference for them, and don't really use them. I love the tremolo, I can now get a square wave that can be controlled by momentary switch, and where I can set the speed by tap tempo. I have only toyed with the filter so far, but I think I should be able to actually make it behave like an envelope filter (I'm really not an envolope filter kinda guy, I'm mostly thinking about making space battle sounds by having fuzz in front of it

). Everything plays well with bass, and I don't notice any loss of low end.
The only slight drawback for me was that when doing short bursts of effect (~1 sec), sometimes the pedal thought I was trying to do tap tempo instead of momentary, but that was easily addressed with the external tap tempo switch. I think some of that is my clumsy feet, some of it is the challenge inherent in having three distinct functionalities in a single switch...but I'm very happy with the external tap tempo solution.
