Got mine today. Sounds pretty good as a Bluetooth speaker - up and away on that score within 5 seconds of plugging it in. Not what you'd call amazing as a bass amp. Mine doesn't fart on open E per se... Just reminds you it's not actually a bass cab and could do with a high pass filter about 80Hz! Cutting bass back to 9 o'clock took the stress out of the cab, but sounded a bit pants. It was sitting on my rather cluttered kitchen table during this so I must try it on our solid floors to see how it fairs.
I'm a bit disappointed the app connected feature won't work with bias, etc. The engineer in me had assumed it was basically a glorified fx loop and therefore any amp sim would work. The original iRig worked using the 3 pole 1/8" jack on the iPhone so assumed this would work the same. May fiddle with this a bit... I'm too invested in bias to even consider another app.
Overall I'm not disappointed as it's pretty ("oak" front - actually it's vinyl wrap but looks OK from more than a few feet away!), sounds reasonably good as a Bluetooth speaker, can take bass even if it's not quite a bass amp, and has a lot of connectivity options. Haven't tried the wireless dongle yet.
I still think it was beyond stupid of Ashdown to market this at its original price (look like a 600 quid plus piece of kit it certainly doesn't), but at what I've paid for this I'll certainly keep it around!
