Care to explain that? Go ahead, give it a stab.
I know that I'm talking about.

Glad the nut helped DeeAa. Those guys arent overdriving preamp
Its in the power tubes DeeAa. Preamp distortion is harsh sounding
Usually, but not always. In fact, preamp distortion has more even ordered harmonic distortion than push/pull power tube distortion. The KEY factors are design, not going ape sh!t with the gain, and THE TUBE. For example, a REAL Mullard in a Marshall 2203 or 2204 with the right tone settings and the right speakers can get some very nice preamp distortion.
while power tube saturation is smooth as butter.
Depends on the amp. Push/Pull amps don't sound as smooth as butter, but they do have a distortion tone that is different than preamp tube distortion. For one thing, the push/pull design attenuates even ordered harmonic distortion and favors odd ordered distortion. While odd ordered distortion can sound harsh, there is a magic that happens through the output transformer of the right amp.
You might try swapping out a couple 12AX7's for 12 AU7's and/or 12AT7's., Nicer sounding all the
around besides (I think)
I'd suggest 5751 instead of 12AT7, but I will use 12AU7 in circuits that I think have too much gain to start with.
lowers the voltage just a little which helps the amp overdrive sooner.
Actually it's the opposite. Less output from the tube means that the amp will not be as overdriven. What you are hearing is the difference in the preamp tube distortion.
You dont have to worry about biasing . I dont use a harsh assed 12AX7 in any of my amps.
I've never heard nothing but praise concerning their tone.

Using reverbs and whatnot I managed IMHO also earlier to get pretty close at times, but I wanted it to be done with no FX, just the guitar and the JMP-1. It's all about correct volumes; I have the JMP pretty much maxxed out on the clean channel to get this kind of sound. Don't want to use any kind
overdrive gadgets; that's pure 12AX7 overdrive there.
This is with my now-saddle-and electronics-modded Explorer (BTW,
the bone nut DID make a real difference!) and Marshall JMP-1 +a 4x10" -
IS a bit on the bright side, with my Strat I get pretty similar sound but
has much less high-end bite. Also I have the bass setting on '1' (6 is max) but it needs to be rather presence-biased to achieve enough bite.
HOWEVER I want it a little too bright; there's no EQ or any other changes after the fact, just the explo, JMP-1 and 4x10 and a D/I to pc, no
_nothing_ except a little compression when turning it onto MP3. But
warned and twist that treble on yer systems a little down if it hurts yer ears as it its - remember, it's not what it should sound in a full
but what to work with as a basis before any FX or such.
(Bright is IMHO better because now I can EQ it to fit the song,
than try to boost highs later on. If I crank up the volume, it gets more bassy and softer, but this is recorded at a volume my wife & kid can stand without covering their ears :-)
It sounds almost identical when miked with a '57 or direct in now,
this is mostly miked, with about 35% of the D/I signal mixed in. Using
direct signal somehow keeps the sound more 'intact' just using a mike leaves it a tad hollow, but then again just the direct line is too dead and would need FX to liven it up. If I could crank it I'd probably use only miking.
The only problem is that there isn't enough drive for solos as it its (hence 'malcom') and I need to find a way to boost it even further for lead sounds...the quest continues...:-)
