Just put JJ tubes in my Mark IV

[Lava Man]

I just put a complete set of JJ tubes in my Mesa Mark IV that I got from Bob at Eurotubes http://www.eurotubes.com

I play mostly blues and classic rock and these tubes make my Mark IV just nail these types of tones. I got a matched set of EL34s and 6L6s because I have always like that combination. I got some really nice Stevie Rayesque tones with my Strat in the neck position - I use EMGs and they can sometimes sound glassy on the clean channel - but these JJ's seemed to have warmed that up a lot! I am pleasantly surprised. Can't wait to go to the blues jam this week and open her up!

Most importantly both my gain channels are much quieter now! (It was pretty bad I had not changed any of the tubes in about 2 years...)

i put jj's in my crate blue voodoo, they really brightened up that thing, tho the sovteks that were in there were pretty toasted.

I have all JJ's (6L6's) in my mark IV too. They really work well in that amp.
