I bought these tubes for my sovtek mig 60 and the amp came alive. Very good low end and crisp highs!

marc Vee - December 18th, 2009

I have used the EH EL-34 in the outside sockets of my Mesa/Boogie Mark 3 Simulclass amp. This tube sounds the best for my amp. It is very musical and has a pleasant overdrive quality as well as good clean tone.
