||Re: marshall mod?|
I don't think you'll gain much by moving this tap but you are of course welcome to try!
As Liam said, I'd look at the bypass caps and for adding more bass but I honestly think your problem is the fact that the amp is a JCM900 to begin with.
These are different beasts from all the Marshalls prior (except maybe the Jubliles and the 2205's) These amps use diode clipping and Leds to get all that MONDO gain that sounds fuzzy and buzzy.
I've had more and more people ask me to try and make their 900's sound like the 800's I've modded for friends of theirs. I've seen a site somewhere on the web where a fella came up with a mod for the 900's but it's a serious project that basically turns the 900's into an 800.
The biggest problem is this sort of mod would be pretty pricey because it takes quite a while to do. If you type in "Marshall mods JCM900" for your search critiria i think that'll pull it up for you. I almost think he offered a book that takes you step by step through the mod.
I guess maybe it's time to grab a 900 and mod it so it does sound good! (ha, ha)

JCM 900 mod - the gifs with the schematics are broken links!
Miscellaneous complaints about the jcm900
"Plexing" a metalface Marhsall
Now something controversial. Gil Ayan posted a copy of an article in the boogie-talk list where Richie Blackmore says he hated Marshalls, he wanted his amps to sound like a VOX - he only liked the look of the Matshall stacks. Marshall tried all kind of mods to please him and in the end they gave up and installed a VOX amp inside a Marshall head
Has anyone read this? Gil can you post the article here?

The whole "plexing" bit can be done (and more or less agrees) by matching the 1987/1959 pre-amp circuit from whatever amp you're starting with.
The output tranny stuff is all 100W specific Those imps are 1/2 of what you see in the various 50W units. The 50W Parks used 5K OT's and are supposed to sound the best, so I hear. (not in person though..) The JTM45's wer 6.6K and then by the time you had late plexis with EL34's you're looking at the 3.4K area. (1/2 those for 100W). The older amps just look more like Bassman basically.. Definitely play with the filtering..

I'm would disagree with the fact that he was after the Vox tone. I know two guys who used to work for Blackmore on teh road and a keyboardist who toured with him.
He was a really BIG LOVER of those Marshall Majors. He didn't like alot of distortion and those Majors were LOUD! They used KT88's.
He still buys the Marshall majors. He likes the cleaner distortion on these. He always had these modded with a Master Volume.
For what it's worth;
PS: his tone never really sounded like a Vox to me but that's just my ears

I always thought of Blackmore's tone as the BEST Marshall tone ever recorded (followed by Angus Young and EVH), so this interview sounded strange to me too. Maybe it's fake, or maybe you can't trust what Blackmore says on interviews just like you can't trust EVH or Jeff Beck.
Here are some quotes (thanks for posting the link that Dai):

I heard that Blackmore used Vox AC30 for almost every studio recording only live did he use a Marshall Major.

Here's something Gil posted at the boogie-talk list. I've found it interesting and so I'm replicating it here:

From: "Gil Ayan"
Subject: More on Blackmore
If at any point in time you guys get fed up with my "retro" trends, let me
know and I will pull the plug. However, after buying my now beloved Deep
Purple boxed set (it's been a month and I'm wearing the CDs out), I can't
help myself... I used to love Ritchie Blackmore as a kid, and then the
jazzier players messed with my head. Now, in denial of imminent middle
age, and because my jazzier heroes have decided to "retire" (it has been
one fiasco after another), I guess I am bowing to my old rock heores
again. Without any further adieu, this is a message from my buddy Carl
Fiadino, which I hope you will find of interest.

Gil, Blackmore's sound, pre "Burn" ('74) was his 200 watt Marshalls with a
Hornsby Skews (sp) treble booster, an English brand. This is what you hear
on Made in Japan and the earlier albums. Machine head was aVox AC-30 with
that booster or something like it.
Then, from 74 on, he started using his Revox tape recorder for echo and
overdrive (overloading the input....and still uses it to this day.
To get his sound.
Well, Malmsteen gets close with a DOD 250 driving a DiMarzio Very Metal
pedal. Don't laugh, my buddy photographed his rig a few years ago.
On my tape I played a few Purple tunes with the Guytron, and that was
close, but believe it or not, if I was shooting for a close proximation of
Blackmore...I would use a 4-input Marshall and a Boss DS-1.
Think of the sound Satch gets with his Marshall/DS-1 and substitute a
Strat. The DS-1 has good clear sustain and also the ability to turn the
guitar down at full distortion and it cleans up very well. The thing about
the DS-1 is you must tweak the amp to get the best from the pedal....and
leave the pedal on all the time. Things like Fulldrive II and overdrives
aren't going to get the sound...neither are buzzy high gain amps.
I'm glad I sold the Guytron. I used it 5 months and tuned a $300 profit on
it due to the Guytron buzz. I used the $$$ to "undo" a mistake I made and
ordered another Bogner.
