I was playing thru a LMII for a couple of months and I thought it was a neat little amp, but I found that I like Class A/B Amps more so than Class D so it's back to the old Aguilar DB750 for now,however I've been eyeing the Epafani UL 501.It's 850 watts @ 4ohms ( not that I'm sure I need that much power anymore) and it's class A/B but there's nothing wrong with MarkBass if that's what a player likes
I think the LMII/LMIII are the only one's without a mute.
