Mine is the V1 version, I bought it new in 2010. I've ran it with a hell of a lot of amps, Markbass LMIII, GK 1001 and 2001 RB's, Genz Streamliner and Shuttle 9.0, Trace Elliot Hexavalve, TC Blacksmith, Orange Bass Terror and currently an Orange Four Stroke 500.
The only amp I feel it didn't work with was the Streamliner, it sounded way too 'flubby', if that's a word, no real definition no matter what I did, to be honest I didn't really get on with that amp at all.
I use it in two bands, one is a Ska/Two-Tone band and the other, a Punk band. Always a P bass (with flats on at the moment) in both bands. I have never felt it was too boomy, apart from with the Streamliner, but I do like a bass tone that sits under the band, saying that, with round wounds on I can get pretty close to JJ Burnel's bass tone with the right EQ settings. What that sounds like out front, I do not know but I have had lots of good compliments from other bass players on my tone/tones. Alex told me that there is not much treble on these cabs and the output drops like a stone at about 1.5Hz, but I have never felt wanting for top end.
