I play the MM68 when I need to plug in and it suits my needs very well for that. Unplugged, it has an average sound - but reasonable. Plugged in, it sounds great. It's quite sturdy (which is nice when I play in bars). Overall - a great stage instrument.
I wasn't that impressed with the lower lvl models. If you are thinking of buying - I'd recommend spending the extra $$ and get the nicer of their models (MM68). I'll bet you like it.
