EVH live rig circa 1981

330uf/820 C/R at V1a
.68uf/820 C/R at V1b
.022uf V1a coupling cap
.0022uf V1b coupling cap
100k V1 plate resistors
100k V12 carbon comp plate resistor...I'm guessing it might have measured a little high like mostt CC resistors...?
.68uf mustard/820 ohm resistor w/440uf electrolytic paralleled over the .68uf mustard
470k mix resistors w/ 500pf silvered ceramic LEMCO dogbone cap for bright channel mix resistor
33k/560pf in the tone stack cap
all other coupling caps .022uf
.1uf/5k presence
100k/ 4 ohm NFB setup

The OT was most likely a custom wind from a guy named Arson at Valley Electronics; Jose used to get his OT's from there from what I understand. I hear a higher primary impedance, but I could be wrong on that.

Sylvania 6ca7s in the power section biased to 80ma at 120v and dropped to 90v.

I think the effects chain in 81 was a Phase 90, MXR Flanger, Boss GE-10 into an EP-3; I think he was using a w/d setup with an Eventide pitch shift and a different delay by then too...someone correct me if I'm wrong on that.

4x12's with Greenbacks and particle board backs; I think the JBL D-120s were gone by then too. I think it was TubeTramp that said he had switched over to GE 6550's for reliability issues around this time. I do hear a drier, more scooped tone in the Largo 82 clips that seem to match up with what I hear from 6550s vs the 6ca7s. This was also around the time he killed one of the coils in Frankie's PUP. His tone did seem to get brighter and thinner around 81-82.

The only difference is i'm on the 8ohm tap and only .68u on v2a and im using a 2.7k on v1b.
using el34's.
all carbon film resistors.
5000p on bright volume turned up to 8.

Don't be stingy.......

Makes one feel sort silly with all the fancy racks, pedalboards, switching, etc. when you take a look at that gear piled around the studio! I have only seen that pic zeroed in on the back of the Marshall, but not the rest of the photo. Thanks..........

Steve

Whoever said it was a stock MArshall when they saw it did not lie. It was not stock when Ed had it.It was returned to stock later. Do you not see the extra pot on the back of the Marshall?

That's not a pot. It's one of those pop-up thermometers to show when the amp is warmed up.....

 

[nitro]

Metro amp is NOT the place to go, some over there have dust for brain's,you can share good information with them and the still dought you, name calling all that BS,but they still look for information regardless of the information that you just shared with them is correct,go figure............

Killer as always Mark; that low-end is the perfect blend of chewy and percussive! You've almost got me convinced that 100k/ 8 ohms is the way to go. I do want to try a 500pf-1000pf cap over the NFB resistor with 100k/ 4 ohms first. I'm also wanting to re-visit a lower value V2 fat cap; I just don't think anything over 25uf is necessary; it gets too muddy. I might try something a little closer to 1k at V1b as well. Supposedly Ed's V1b cathode resistor had drifted up in value. I'm wondering if his V2 plate resistor didn't drift up as well; I'm thinking that might help smooth the top-end of my amp and give someneeded compression. Ed's V2 plate resistor was CC as I recall from the pic, so I would think it probably measured a little high anyways.

Killer clip man!

A very good friend of mine briefly helped setup equipment when they played a show near his college about 1984 and he got to touch and check out Ed's rig up close (which is the one pictured above) and he was told most of the Marshall's were bone stock. Just lots of amps and lots of volume.

put a pot in place of the feedback resistors and listen on the fly. im not sure i agree with a cap over the feedback resistor but i'm all ears once you try it.
i believe you are correct, anything over 25u does nothing more than boost freq's that are not even audible in a guitar amp.
i don't think a Marshall ever used anything but carbon film resistors but i could be wrong.
keep on tweaking.

That component list will be found carved in a cave wall hundreds of years in the future and cause much discord and confusion, as the bright cap value is slightly off.

5000pf...2 out of 3 cavemen agree.

no offering of how it is off? hmmm

I read somewhere that he only ran something like 4 heads at once and he didn't have this rig for too long.

 

[OBGYNkanobi]

IMHO, this was about the time his tone started going down hill. I'm sure his amp changed over the years jsut as his setup did. I'm just using the specs Dave gave as a jumping off point...jumping two lead'ish channels with a few tweaks to squeeze out a little more gain and sustain. What I'd really like is to have something b/w early VH and Joe Holme's Ozzy tone; now that would be my ideal. I may have to look into a passive loop at V2 with a PCM-41.

I was being facetious....

 

[nitro]

Amp was a Jose modded marshall,effects the same as women and children first(phase 90,flanger,echoplex).Just buy a amp from Rockstah and be done with it.

^^^^
Not that Steve was asking this.... but this.
All the roads lead to Rockstah's stuff now...

 

[Stramm8]

The only problem with all of these theories is that they are just theories. My theory is that it's just a slightly tweaked, cranked, variac'd Marshall. The Metro-Friedman is a prime example as it pretty much nails the tone. There is no evidence he was using a "Jose" modded Marshall. If he did, his tone would be doo doo

 

[fluff191]

I thought the pot on the back of that Marshall was left from when the amp was a house amp at The Whiskey?

 

[Chubtone]

That would be my ideal too...... and I already have a PCM-41. Joe's amps are clearly Jose mods and should dispel any rumors that the Jose stuff didn't sound very good.
