title says it all pretty much. ive had my ac4 for a few months now and it sounded pretty good out of the box but i decided to swap the tubes the other day for shnits and giggles. i pulled the stock sovteks and loaded it up with jj's. i noticed off the bat that there was just a tad more hair on the notes than there usually was at cleaner settings, there seems to be a little less headroom if you will. the up side though is now it sounds even better when i turn it up, not that it didnt sound good before, it just sounds a little richer now. overall i like the way the jj's sound, but im going to try putting a 5751 in the preamp and see what that does. anyways just thought i'd share.

if any body else has swapped out the tubes in there ac4 please let me know what your outcome was

I've looked into swapping the valves a few times but haven't done it yet. Good to hear from someone who has though, wouldn't mind lowering the headroom a bit, on 4 watts it takes a bit of volume to breakup.

How does your Rat sound with it by the way? Considering getting one in the near future.

jj el84 and a tungsol 12ax7 was fine, not that different.
I will use them when the stock tubes need replacing.

But changing from the 10" to 12" speaker was a big deal.

Thanks, I actually had a Russian Big Muff but ended up trading it away. Sounded great but wasn't for me at the time.
