I never knew how much tubes affect the tone you get until I retubed my blues master with Electro harmonix 12ax7, and I realized the EQ wasn't doing much, no matter what I have a really fat. bassy tone. Then I read that the tube is favored for hard rock.. After a while i eventually started liking the tube though, I had to put the bass at 0, and cut some bass and some treble with a boss EQ.
This is the tone I pulled off with the blues master with the EH tube, rather then the sovtek that's usually in it. http://soundcloud.com/dizzydoctrine/something-cover
I also got to thinking that possibly JK is using a EH 12ax7 with his.. or a tube similar ,the tone sounds very close..
But besides that.. I was wondering some good tubes to upgrade too, and the tone that some offer. I'm going for a cleaner sound, but that sounds nice with a little clipping as well!
Any advice is greatly appreciated!
