Just picked up a used Mesa Bass 400+ sportin' JJ outputs. I like it. It's a bit dirty sounding, but I have no doubt I can tame the gain situation. I'm enjoying the flexibility of the preamp (reminds me of a nasty Pultec to be honest) and I also see why few people questioned Mesa's advertised power rating. It has two settings: loud and off. Anyhow, with Mesa discontinuing it, I figured I couldn't pass on a good deal. This one looked lonely. Now it has a plethora of tube brethren and a whole bunch of cats to love it.
