Here is curve ball...
I would describe my SMS as Warm. My Mesa set up clean though a JBL K120 is really bright. Comparitively ...my SMS > Mc is warm. I read thread after thread talking about the "ice-picky" nature of this rig, and I just cannot get there. I've even seen it across two diffent Mc Amps (250 & 2100). When the volume comes up is brightens up some, but never to ice-picky. I wiggin' out about this whole thing. The rig brightens at volume, but not hugely. Treb @ 10. Mid @ 5.5. Bass @ 0. Bright switch in the middle.
Adamas > Strat > Waldo Buffer > Dimarzio Super 2's (split) > Tone controls Wide-Clyde > Mogami custom cables > SMS > MC250 > K120 (in SoundScaper copy open back) = Warm. Lush. The rig growls nicely, and is very responsive to pick attacks. I've been playing with a fatty pick for 3+ years, but still...
I love that '76 - '78 brighness. I hear it across the TB's & with Wolf. I definately hear some "Warmth" creep in with the advent of Tiger, and really...my rig sounds much like '79-84 is. I don't listen to much of the 80's stuff, because I saw tons of that stuff.
I think I'll haul it all to PDX & let Pete B. play it. My Treble knob needs an "11"...no really ...what we all need is The Eleven
