Mesa boogie substitute tubes?

[surferdeac]

anybody have opinions on the mesa boogie substitute el34's str450's or the SPAx7a's for use in ace head instead of their stock tubes (str447's / 12ax7's)????

could these substitute tubes help out with what some people consider excessive brightness and harshness in the high end of the ace heads??????????????????

You'd probably get a more dramatic change in tone with a change of speaker. The SPAX7 is designed for low-noise, the tone is not that much different. STR-450's are da bomb, but the change in tone is like the difference between really expensive Belgian chocolate and a Hershey bar. And no one in the audience will hear a difference, although they will notice the grin on your face.
