I am buying the llB. I called Mesa and at first Chris said they never converted any llB's but then I told him the serial number and he said, "yup, it's a C+, it was here in 2011." I mentioned dodger916's llA and from my research there seems to be around 10 llB conversions out there. I'm just waiting for some pictures to make sure it's not all beat up. One man's mint is another's "well that's an easy $5 volume pot and Mesa said they could fix the GEQ" mint. Not kidding, I see "mint" Boogies constantly being sold as mint missing pots, EQ sliders, etc. and it's always a $5 fix. This amp has been on CL for some time and he won't budge on the price, bummer. When I bought my stratocaster as a kid, everyone thought I was crazy. 35 years later, if I didn't love that guitar more than money….. I still own ENRON stock and was laughed at when I wanted to buy 100,000 shares of Apple @ $12 (it went down the next day).
