I'm keen to check one of these out, for sure, but I wish you'd asked ME what features to include as then this otherwise perfect looking amp would have at least one 9 volt output on the back to power a tuner ( or other) pedal. That's got to be a good, useful and relatively cheap feature, surely? I don't want you to feel too bad about it, though; I've been playing for 50 years, owned scores of amps and only just thought of it myself...
Next time, maybe...
