This is absolutely THE best bass head on the market. The LMIII has made some improvements with better components and a few more features, but the LMII is the stripped-down original that really put Markbass on my radar. I've sold two of these heads in the past and immediately regretted it both times, so much so that I'm on my third LMII in as many years. I love that this amp is essentially colorless, meaning I can paint my tone with my pedal board and just with my basses' natural characteristics. There's very little to fiddle with on this head. I love it.
