Rebel 20 Tube Compliment?

I seem to recall at least one other player here who recently bought an
Egnater Rebel 20 amp....maybe more?

These things come loaded with Groove Tubes...but of course, unless you
can identify tube brands just by looking at them, you really don't know
what you've got. (I'm not that good at ID'ing tubes--yet.)

I loved the tone of mine, right out of the box. But....being the
experimenter I am, I can't help but wonder what a different tube set
might sound like.

Any Rebel 20 owners try swapping tubes? If so, what did you try....and
what did you think of the result?

I'm considering trying some Tung-Sol 12AX7's first...

Comments are appreciated!

Mike
