I have a little problem. I play a rocktron voodoo valve preamp with a marshal EL34 100/100 power amp.
The sound is really amazing. He is very rich but not artificial like other rack elements.
It sounsds like a more precise amp head.
The only thing I don't like so much is one frequency in the highs. Whatever I do this frequency is already there. Not that she sounds harsh... But a little bit brittle sounding highs.
I think it's perhaps the typicaly British EL34 touch ?
Anyway.... I play metal (lamb of god, god forbid, pantera, alice in chains stuff .....
I know everybody's here will say "change the tube for 6L6"
But I'm not a big fan of 6L6 ...too dirty Mids and not bluesy enough (I love playing blues and for that the EL34 are awesome. )
After many researches I read that KT77 tubes could be a good alternative for me...EL34 sound with the lows of 6L6 , more nuanced Mids and beautifull highs... Not brittle like EL34's.
So here is my question. What do you think about that. Is here anyone that tried and compare these 3 power tubes?
What do u have to expect?
'Scuse my English.... I'm french and I do my best ^^
Thanks to everyone here.
