Replaced the JJ power tubes in my Nomad 45

[Rocky]

replaced with with Ei's and the amp is now WAY better.

The JJ's made the amp sound like it was covered in a wet blanket. This is the third amp that has sounded better to me after ditching the JJ tubes.

what about the preamp tubes ?

where did you buy the EI's from? 6l6 or el34 or the 6ca7's?

I agree. I put JJ's in my DR a while back and I had to crank up the presence and treble in order to get the sound that I wanted. A lot of people say that JJ's get rid of the "fizz" and harshness of stock Russian and Chinese tubes, but at the price of giving up crunch and dynamic upper mids/highs IMO.
