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.
Interchangeable !== identical, though.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

Cool info. Can you translate that into tone and feel for the less well versed please?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.
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.Interchangeable !== identical, though.

Thanks Levi! The preset sounds great.
Are you still going to do the tutorial video?
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.
Thanks, Chumbucket! Yes, I am working on it!
