Chrisola's old MKI HT-5 arrived this morning and it is Wonderful.
It's quite small and easy to carry. Even at bedroom volumes it really sings, and it has the largest range of usable tones I've ever heard in an amp: really flexible. I've given it a quick crank it I reckon it would compete with a drumkit just fine on distortion, though not clean.
Unfortunately the headphone out is missing something- can't place my finger on it. It's still a world ahead of non-emulated outputs but I'd much rather play it through the speaker.
