I bought one from Amazon about 3 weeks ago. Awesome toy/learning tool/backing tracker/bluetooth speaker/computer interface. My Mac is a bit too old for it, but the Ipad works fine, as does the phone. Great tonal flexibility. Next gen will prolly have a footswitch and line out. Sounds great, can hold its own with a sane drummer, and loud enough for all but huge gigs, in which case a mic in front will rectify that deficiency. DOES NOT IN ANY WAY REPLACE BANDMATES OR TUBE AMPS! Essentially a practice amp punching way above its weight/price. Sonically it can hang with any other modelling device, and that's with 2 nondescript 4 inch speakers. No Linux support yet, but works fine with Apple or Android. Dunno if I'd seriously consider gigs other than solo or duo, but the tones you can preset yourself will work without the app, so it is gig-able as a stand alone unit. Not sure it's built with serious road use in mind, but it's a sweetheart at home. Steep learning curve, already has user forums set up, along with modding ideas from advanced tinkerers. I could gig with it with my small pedalboard for an instant boost for solos. No wah features, so your own wah pedal could be added to your chain. Every other useful effect is there, and all are high quality. The parent company is well established and regarded in the industry. It' a true home run!
