I'm a singer/rhythm guitarist in a punk band, so to be honest this pedal is overkill for my needs, but I had a bit of spare money and wanted to see if this lives up to the hype. It does.
Positives: So many sounds in one tiny box, access to any number of amps, cabs and pedals. Basic sounds are pretty good and with a little tweaking can be highly personalised. The case feels very solid - the pedal is heavier than you expect. The delays and reverbs are very nice.
Negatives: The writing on the screen is a little difficult to see. The app, while intuitive, is not terribly easy to use (the sliders go all over the place) and I've had some problems with Bluetooth connection to my iPad, although not to my iPhone. Also, I really bought this pedal to add effects like chorus, reverb and delay - I already have the overdrive sounds I want from my Blues Driver - but I find the chorus on here to be a little weak and one dimensional. And of course, you only have the one switch, although that isn't actually a problem for me as I'm only going to be using two or three patches and can cycle between them.
That said, I've already set up a simple Marshall JCM800 patch and another one which emulates a Vox AC30, and both sound very, very good. Just for that, this pedal is worth the money. It won't be replacing my BD-2, but it is already sitting next to it on my pedalboard and I can't see it coming off for a long time.
