EVH tone deep dive feat. DAVE FRIEDMAN and PETE THORN

[levipeto]

Cliff! Pretty please!
How can we emulate the 50K mid pot?

 

[R.D.]

How much should we lower the Negative Feedback to emulate 47,k off the 4 ohm tap ?
How much should we increase the Grid Bias to account for the Variac @ 90 volts ?


And Dave Friedman just spilled that the Fat Cap on V2 was 470uf ....

great video

Completely enjoyed this earlier today....I love geeking out to VH tones

Looking forward to Cliff's answers to the questions above!

I’m glad that I’m not the only person who sees videos like this and immediately starts wondering whether we can do that in the Axe FX

 

[Dave Merrill]

How about the 6CA7s running at 90V? Do we need to do anything so the bias is adjusted correctly for 90V?

 

[Dave Merrill]

And agree, awesome vid!

A good hunk of how that sounds is also Pete.
Looked like he's picking pretty hard too.

 

[Rock Chalk]

Very cool video......thanks for posting.

Set the Variac parameter in the Amp block at 75% to simulate 90VAC to the amp.

6CA7's are in the power tube options.

I believe pulling the negative feedback from the 4 ohm tap instead of the 8 ohm tap would give half the voltage, so I would guess reduce the default negative feedback setting by half.

How about correct biasing for 90V?

And no offense, just reacting to your stated uncertainty, can we get confirmation on the effect of the negative feedback tap location?

 

[jmpatrick]

Did I miss something? There was no mention of the dummy load into the SS H&H power amp. Maybe that was just for live stuff?

Should be 70.71%. To end up at half, it would need to be 1/4 the impedance.

 

[mr_fender]

Ah that's right, half would be if going from the 16 ohm tap to the 4 ohm tap. Thanks.

Awesome video! I am feeling inspired now after watching this! Thanks for sharing! I still think Eddie's best tone is on the 1984 album, but this deep dive nails the earlier tones! So good!

 

[guitarzen]

Wow, awesome video! That may be the most legit VH tone I've even heard, probably because it's done correctly and not half ass. Great knowledge in this deep dive.

 

[Holbert71]

This sounds damn close

 

[levipeto]

This sounds damn close

That's a 5150 III amp. We are geeking out about the Plexi here

 

[LeBigMac]

Did I miss the Echoplex preamp? I think they didn’t mention it.

 

[flcmcya]

Pete's definitely full on Halenholic!

Hehe didn't start slaving until the 1984 tour, and he didn't use to slave when recording.
