Re: Obsessed about AC/DC sounds

Keith,

Your lack of response has been noted.

Care to explain that?  Go ahead, give it a stab.

I know that I'm talking about.

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



way

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.




What amps?


I've never heard nothing but
praise concerning their tone.

Phew, well, now I think I'm close enough for my purposes.
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



of

overdrive gadgets; that's pure 12AX7 overdrive there.

This is with my now-saddle-and electronics-modded Explorer (BTW, 


Keith,

the
bone nut DID make a real difference!) and Marshall JMP-1 +a 4x10" -



it

IS a
bit on the bright side, with my Strat I get pretty similar sound but



it

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



FX,

_nothing_ except a little compression when turning it onto MP3. But 


be

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



mix,

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, 


rather

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, 


but

this
is mostly miked, with about 35% of the D/I signal mixed in. Using



some

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.

Comments?

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...:-)
