Picked up an old SIR Marshall

Again, wrong on ALL counts. Funny how right before Frank was supposed to introduce his home brew amp, that he does an interview and tries to change reality. Frank was hired to COPY Caswell’s modded 71 SuperTrem, #39, the amp EVERYONE wanted and was impossible to get. SIR wanted more like it for obvious reasons. Lynch himself tried to buy it…and instead rented it for the ULAK tour. In an interview Lynch states that he finally found out who modded 39…Caswell….and had him mod a few more for him.
These are the facts, and true history of that amp. Not the made up bullshit by a guy who decided right before he started his own amp line(which never materialized btw) that he’d tell a tall tale to drum up business for himself. In Levi’s interview he states that no one wanted to rent #39….what a joke. There’s at least 5 interviews where Lynch, Slash and others talk about #39, and how it was ALWAYS unavailable.
Levi turned into a good liar, that’s for sure. It’s too bad because he did some cool mods…but his half ass attempt to change history is sad at best.

I was goin gto say..doesn't matter end of the day as Levi's #36 mod is raved about (isn't it on AFD while 39# is on the demo?) and his #34 mod is what is in Slash's favourite UYI amp? Then there is also a #38 which i think was a variation on #39 too.

Room for both guys. I thought Levi did some stuff for Demartini and a few others as well but not sure if that is from Samhain or if it is from some other site i went down the rabbit hole on once upon a time.

Frank was hired by RATT first 2 albums fulltime & on the road. The SLO wasn't even invented at that point.
Billy Squire "Lonely is the night" that Kerrang is a Levi amp. Many others.
Franks work stands alone but he was a real low key humble guy.
 
Have you tried a pedal or two in front of it? My 72 is a damn monster that blows the doors off any amp I’ve owned or played, when I double boost it. Better than either Wizard or C+ coliseum I had. It’s also a fairly clean tone like a SB.
That's actually what the tech suggested. Leave it stock and use some pedals.

Give it a shot....I found out that my 72 is just a force of nature, a killing machine of steamroller tone that I never imagined it having...I just wanted a cool 73 or earlier NMV Marshall to have, even though it's impractical to gig with or even open it up like that at home.
But, after experimenting with different pedals, I found that double boosting with a cheap Boss OD1X and an even cheaper Ultimate Drive (OCD clone) turned it into a monster..It sent a nice 83 2203 packing, and any Wizard GAS I had after selling a nice MC100 went away.
Be warned though; these 100w NMV Marshalls with a boost in front can push 200+ watts...use an appropriate cab(s) so you don't fry any speakers.
 
Got it back yesterday. The tech who's an old school guy loved the amp, said everything looked perfect and to leave it be. I tried it with some pedals and it sounds great at pretty low volume. Without pedals it starts breaking up at about 5 which is painfully loud. Cool amp but not really practical for me so probably gonna let it go.

The more I read that term “Kerrang” I think I refer to that tonal thing as toothiness/teeth. Like, I’d say, “that Marshall is toothy.” Or, “that tone has teeth.” I heard it read that somewhere and it stuck with me when someone was describing hot rodded Marshall tone. Basically, Kerrange = Marshall upper mid range roar.

Before you off it, try it loud with a pedal or two in front. If it’s anything like my 72, you’ll never sell it.
 
big fan of semi clean marshall tones hit with pedals as well. pedals have come a long way from the 70s!
but if you can get the amp to do more of the heavy lifting it always seems to be a bit more satisfying.

from my perspective as a guitar player who came of age in the 80s and a decent live sound engineer for 30 yrs, the tone lynch got on the ulak tour playing irvine meadows amphitheater was one of the two best live hard rock sounds i've ever heard, and light years better than the previous tooth and nail tour tone which i saw at magic mountain.

the other great one was gillis/ozzy at neil blaisdell arena in honolulu with the boogies and his red strat. both examples had that amazing clarity and grind, endless sustain, and string to string note definition and body. sounded like the biggest dirtbike/chainsaw full throttle fury with hair trigger touch sensitivity and dynamics. but don't discount the effects side of the equation....lexicons?

steve vai with roth on eatum and smile at the forum would be third place with his bradshaw wdw rig and perhaps jose modded marshalls?

beyond that, in various degrees of marshallesque tones...

yngwie : alcatrazz at university of hawaii ballroom, riging force at pomona valley auditorium, marching out at neil blaisdell, trilogy opening for ac/dc at long beach arena, all great strat/marshall rock tones and honorable mentions. plexis with dod od250 pedal and roland delay.

after that, landau at the baked potato with his OD100/bradshaw mini rig, ej at the coach house in san juan capistrano on a via musicom, paul gilbert with racer x using unknown stuff (epiphone coronet/ada mp-1/ampeg v4 cabs..?) at the waters club in san pedro,

for reference, i also saw warren on the first two tours, slash on appetite open for aerosmith, VH, and so many others in their heyday.
 
"Rock and Roll Hoochie Koo" was the song that turned the light on in my head.

There was probably a dozen or so of us friends hanging out smoking pot and drinking beer at a pavilion after school, circa 1978. A couple of guys were playing their guitars. Playing every song wrong. They had music books for Beatles, Stones, Hendrix, etc. with the chords and lyrics. Hideously horrendous, butchered timing, untuned guitars and everything was just wrong.

I had to say something, something like, "that doesn't sound like way the band does it" to which one of them said, "here, let's see you play" and for some reason I played the beginning of Rock and Roll Hoochie Koo, on an acoustic, just like it sounded on the radio. I had never played that song before but it came to me so naturally because I could hear it in my head and was finally at the point where I was learning songs playing along with the record.

Mic drop. It was done. I remember going home that day and really dedicating myself to playing like Hendrix, Skynyrd, The Outlaws, Clapton, Trower, Rory Gallagher, Uli Roth and all the guitarist that jammed real hard. I had established myself as the guitar guy in that crowd that day and to this day I still occasionally jam with them or they come see me play when I'm playing somewhere.

I did eventually get to hang out with Rick, in 2008 after a show, buy him a drink and tell him what an influence he was.
 
I don’t want to derail the thread but it’s already happening….


Why so some old marshalls break up at reasonable volumes, some sound great, and some stay clean until 10 and barley break up there? I had some old marshall’s that never broke up no matter what and it drove me nuts because you can’t mod them so you either live with it or sell it.

With the older NMVs I've learned the Bass and Tremolo circuits are cleaner sounding i.e. not very distorted until you are close to diming them. If its a Lead circuit it should give up the goods sooner, if you are after natural distortion and don't want to use a pedal to push it. The cleaner amps can be modded to more of a straight up lead circuit as well. The 72 50w leads are kind of known for having more gain than any other year...I haven't played one myself. But this 72 50 is YJMs amp of choice because of this. For me, the 72 Trem is the first NMV Marshall I've owned that is STOCK without an MV mod...I always returned or sold other vintage NMVs because they just didn't sound that good...with or without a pedal....and every one had a MV mod. I'm convinced that I passed on some GREAT vintage Marshalls that just needed the MV removed to shine.

When it comes to pedals and these old NMVs, understand that since it's not a MV amp, the pedals also push the output of the amp to ungodly levels, some say at least 200 and up to 300w! Insane...so while the pedal adds unnatural 'diode' distortion it also makes the amp produce more natural distortion as well. So putting a pedal (or two) in front of a NMV Marshall isn't just adding the pedal grit, it also makes the amp produce more by pushing the output section to ridiculous levels.

That's exactly where I'm at.
 
The pictures aren’t HD, but it looks like a pretty stock Plexi, not a JCM800, that’s why you don’t get much gain at human volume levels. The bright cap seems to be a silver mica cap, so with a low 100 to 500p value, as opposed to the more common 4700p. This difference in Plexi amps account for a later (100-500p) vs earlier (4700p) breakup.
