Hey Chris,
I agree, the LMII is definately a nice amp and I do like it.
Oh, BTW, I haven't been thinking about a WT-550; I've been using the WT-550 for the last 3 years + and now have two of them. Truly wasn't much to think about though. With the right cab set-up, just plug in your Smith bass, let it work and be wowed! Really is a no-brainer.
Don't forget about the Eden WTX-260; a 3.5lb amp worth it's weight in gold.
BTW, just received my new Eden WT-1205 today. Oh my! But that's another topic and another thread start.
