Thanks for the advice and comments, a used Zoom B1X Four also looks really interesting as well, I like the expression pedal, shame it doesn't do MIDI out for other uses but never mind. But first I think I'll see if I can get anything out of the H2N in case it has some kind of use as a trainer. If anything else comes to mind, would love to hear about it.
Thanks for the links Skybone + CameronJ
