Very low in noise and microphonics. Sweet top end.
"Mike, I just wanted to say that all the tubes sound GREAT. The GE 12AX7WAs are gorgeous, full and bring out the best in my guitar...I can't even put it into words. Thanks" Matt
I liked the first set of tubes so much I have to order another one to complete this amp. Thanks again Mike!
They are amazing tubes in my ENGL Savage. Beat out Mullards and Tesla e83ccs. Mike B
