AFIII VH Modded Marshall

[Randalljax]

+1

First clip really got me (pun intended). The magic is gone in the last clips, to be brutally honest.

I have to agree the 6550 just had that rawness to it , regardless if its a spot on EVH it was a killer tone

I have the feeling that we're not getting the preset.

Levi has been a great contributor over the years here. I'm sure once he feels it is ready he will post it.

I spent all day setting up a live stream environment. I want to hold a 'reveal' video stream, where I explain what is going on. There is a good chance it will be tomorrow. I am waiting for a dummy battery power supply for the dslr.

EL34, 6CA7, and KT77 are equivalent tubes. EL34 is designed by Mullard, 6CA7 by Sylvania and the KT77 by M O V of England can also be used and sound excellent, I have a pair of KT77's in my Boogie MkIIC+ and they sound awesome

Interchangeable !== identical, though.

EL34 is a true pentode.

6CA7 is a beam power tetrode with roughly equivalent but a little up-rated, tougher specs.

KT77 is a 'kinkless tetrode', the Euro term for a beam power tetrode, again with some improvement in specs.

Screen current draw is generally a lot lower with KT77 and 6CA7, due to the electron stream forming a 'virtual suppressor grid'. They would also show less delta on screen current, which modulates the phase inverter and preamp supllies less - though it would still be a couple tears in a pint of sea water, compared to the plate current delta's effect there.

Cool info. Can you translate that into tone and feel for the less well versed please?

I didn't want to go that deep, but these 3 tubes can be used without rebiasing to give a different flavour to one's Tube amplifier without risking blowing it up. I never said they were identical, I said equivalent.

Thanks Levi! The preset sounds great.
Are you still going to do the tutorial video?

Thanks, Chumbucket! Yes, I am working on it!

 

[capt994]

Thank you Levi! Having a blast with this preset!

 

[Freds55]

As you may have noticed I have been chasing VH tones. I allways used the Plexi 100w as a starting point.
This time I tried to dig into the Plexi 6550.

Just came across your VH video awesome I love it

 

[rickster71]

want the eddie van halen tone? Mooer pitch box nails it to a T

 

[teof]

Thanks, Chumbucket! Yes, I am working on it!

Thanks Levi! This is a really good preset. The rawness is of amp with a touch of the phaser just tasteful. Looking forward to your tutorial to gain some insights on how you go abt designing the preset.

Levi- Thank you so much for this excellent preset . Have one question , does anybody have a link to a working AxeFx III version of the PT20 cab block ? All the ones I've been trying have no output ... I'm sure I'm doing something wrong .
