Hey j4q0, Now I've heard a Mullard short plate (in MP1 V1 with Boogie STR/SPA in V2), the Mullards open up your sound and are very articulate and will suit volume riding but there's so much gain in 3TM as MJMP says. The Mullard long plates have more depth (but that's in my MP2), I found the 1 short plate in MP1 went the right direction. But as I run 2 long plates and love it, I wanted more
. Theoretically the short plates should be less microphonic than the long plates, maybe at super high gain ?? but I haven't noticed. So an approach might be grab a few Mullard long plates and/or short plates, and try adding them one at a time from V1, V2, V3. You may find just one in V1 works for how you want it to sound ? The boogies are nice tubes , great feedback mmm
best I've heard BTW but a bit 2D, tight, not expansive. But the Mullard short plate in MP1 V1 with Boogie STR/SPA in V2 makes quite a difference. One comment MikeB made after he put them in was he had to be more articulate in his playing (as they track everything so well (good and less intended LOL)).
These are high gain tubes, but the articulation shines through even with copious distortion.
