However there is an issue I tested with my plexis. You can’t get the sustain of rwtd or the crazy sustain he shows in some live shows without a boost in the signal like the pultec meq 5 or the Schaffer Vega with a stock 12000 series and apparently from the infos gathered until now he didn’t used them live on vh1 just look at the Japanese pics.
Dave Friedman and Ohsie Ahsen both believe that something very different and weird was probably going on for VH1 they even discussed it recently on tone talk. Even the YouTuber psionic audio commented in YouTube whatever was there was removed a long time ago. Dave and ossie said it’s impossible for a stock plexi to have this broken sound with this amount of gain and sustain with the equipment he was using at the time. People often said that the live early days of Van Halen sounded even better than the recorded version and George lynch is a testimony of it. There are multiple times where he says that many times they sounded better even live. So I doubt the studio magic was the cause of the tone it was more a polish added in the end. Of course it made the sound we all know. If you listen to Van Halen 0 you can hear an amp that has this broken sound but that isn’t complete yet. It hasn’t yet the levels of gain we know. In Van Halen 0 the sound is closer to a stock plexi. This is probably the stock 12301 in 1976 without the definitive mods that were in vh1. You can hear it still sounds amazing because Eddie plays it but there is way less gain and sustain.
The Zero demo was produced by Gene Simmons who flew the band out to record it, who knows what amps and equipment Ed had, it has been said it was Ace's Marshall's.
At this point since you won't acknowledge the gain a variaced plexi puts out proven by actual clips I think you are punking us to elicit a discussion which I am more than willing to oblige.
It's possible that Ed was not shown the variac/slaving trick yet in 1976 and he was bitching about how loud the plexi was and either Jose or someone else or Ed figured out turning the variac down lowered the volume levels and then he need to reamp them with slave amps. Alotof people including Mark Cameron say this load box was similar to the one Ed used.
You keep saying a 68 plexi can't produce that amount of gain and I have already posted numerous clips of them producing VH1 levels of gain without Ed playing them that sound just like the album and his live shows. The live shows from the 78 tour did not use the mic preamps or the Pultec EQs.
Gear used: EVH Stripped Series (Stock), MXR Phase90, Clinch FX EP-PRE, Suhr SL68 Variac-Mode (everything on 10), UA OX BOX.
Another clip from Gaustad
The amp is my '68 Marshall Superlead (all stock), every knob on 10 - Variac is running the amp at 85 volts. Its plugged into an old, "peeled" Marshall 4x12, loaded with 2 x JBL D120s and 2 x Celestion Greenbacks. Two mics (SM 57s), one on the JBL and one on the Celestion. The cabinet is isolated in my "iso booth" AKA bathroom shower stall, and covered with a moving blanket. On the front end of the amp, it's just an MXR Flanger, Phase 90 and original Maestro EP3 Echoplex. The eq on the pedal board is only used live with a wireless system. The guitar is my VH knockoff - Northern Ash body, maple neck, standard term, non-locking tuners, slightly overwound PAF (8.9K-ish) style pickup, with Alnico 2 magnet. The recording setup is Apple's Logic X using some Waves plug-ins (API 550 eq, LA2A compressor and 1176 compressor) Reverb is an IR of the Sunset Sound, studio 1 chamber.
Here's an in the room I phone clip of Gaustad so the UA's preamps and Pultec's and Sunset Sound settings are not in this clip, it's what's coming out of the cabinet and it's VH1 gain.
