I'm running it bridged with it cabled properly. From looking at the meat smoke, it seems rather dark. More suited for heavier music. I like the tone hammer sound, but I don't like how the boost is controlled, or lack of. Maybe one if their preamps, but I don't see much info on them because they are older models. Just trying to keep it simple with a single tube pre that will work for the music I play, no love for the ampegs?
When i purchased the meatsmoke, I was also concerned that I would be too dark. This is simply not the case. The EQ is very wide ranging and flexible. I find small changes are often all i need. There are a couple of characteristics to the MS that I think are key to its sound. The lows are slightly wooly and pillowy, but still well defined and with a lot of depth. The low mids are more present than in other pre-amps. Mids and highs have a nice shimmer, articulation and liveliness provided you set the gain staging correctly. One thing I do recommend is replacing the tubes. The stock JJ's are harsh. I got some from Doug's tubes based on Doug's recommendation. They are a Ruby 12AX7AC7 HG+ and a Ruby 7025SS HG. They are fantastic in this preamp.
