Found one of these in a local shop, and was quite impressed! Now, when I first plugged in and turned on the amp, the volume was set at about 2 out of 10. Holy! You should have seen the sales guy jump! (Okay, I did too.) I really was not expecting it to be that loud! I started off with a Telecaster Squire to check out its passive vibe. In general, the tone was good, but I was also very aware of all sorts of spurious background sonic garbage. Killing anything that had a button associated with it helped only slightly. I quickly replaced it with a MM Sterling, and was rewarded with a much cleaner, usable sound, but there remained some rattling and buzz that I just couldn't locate. It only appeared when I played, but I couldn't tell if it was the combo itself, or whether it was causing all sorts of other stuff in the room to vibrate and rattle erratically. I also have this notion that neo speakers create sound in a way that just doesn't jive with my ears, based on a few cabinets I've tried, but that's my own subjective baggage. Is anyone who owns one of these combos experiencing any problems with weird noise from it?
