well, we're in luck, as i just happen to have the pertinent issue at hand. ;-)

"We tested   both  preamps  side-by-side,   using    Boogie's all-tube
Simul-Class  2.90 stereo   guitar  power amp  and  leather-clad   4x12
cabinet, loaded with 30-watt Celestions.  The 2.90  uses eight 6L6s to
deliver 90 watts per  channel and takes up  only two rack spaces.  Our
intent in running both preamps through the same amp and speaker system
was to provide a consistent environment for our tests."

while they don't give an exact list of guitars used, they do give some
hints like: "For what it's worth, we noticed that P-90 pickups sounded
better that Strat signle-coils or our collection of humbuckers."
[note: this was in reference to the lead 2 red setting on the boogie
tri-axis.]

and in fairness to boogie, the exact comments on the tri-axis were

"Compared to the '64 Fender SUper Reverb we used as a clean reference,
the TriAxis has a pronounced midrange.  You might call this Boogie's
sonic fingerprint."

and

 "Overall, however, we found the TriAxis' distortion somewhat
processed-sounding, though this is certainly a matter of taste and
playing style.  Also the bass response seems a little loose and
unfocussed.  (Boogie says they tailor the bass response to work better
with a band.)"

and lest people be led into believing that nothing bad was noted about
the marshall...

"Compared to the TriAxis, the JMP-1 hisses like a desert sandstorm at
extreme gain levels.  Excepting the Boogie, however, this hiss level
is no worse than other high-gain preamps or modded heads we've tried."


if there's demand for it, i could be persuaded to type the entire
review in...


from my own experience (and i've only spent a few hours with each
preamp, but don't own either... yet... ;-) the TriAxis and JMP-1
preamps are faithful extensions of previous products available from
their respective companies.  The TriAxis is very remniscent of a
Boogie Quad-preamp with Mark II and Mark IV preamp sections added.
the JMP-1 is like a 9001 preamp with JTM-45 and a JCM 900 hi-gain
preamp sections thrown in.  i happen to like both the boogie sounds
and the marshall sounds (i have both a quad preamp and a 9001), but i
haven't wanted to upgrade bad enough to justify the money.  i think
the bottom line difference here is defined by the type of music you
want to play...


cheers,


bert
