very interesting amp. Lots of different tones out of it too.
I'd guess it's PCB construction, made in China (in the Line6 factory maybe ?), to achieve that price. That's not necessarily a bad thing. We'll just have to wait and see what the build quality and reliability is on them.
I don't like the inbuilt digital reverb and delay. it just seems tacky to me - very "Line6". More to go wrong, more to interfere with the tone. I would much, much rather have a decent effects loop (I wonder if it even has one ?).
generally, quite an exciting new amp though.
