I am relatively new to tube amps (owned my Tremoverb for just over a year now) and never realized how much different tubes affect tone. When I received the amp it had relatively new (so I was told) Mesa 6L6's and Sovtek 12AX7WB's in it. I found it very cold so swapped the 6L6's for some JJ E34L's. This was the exact change the amp needed. I thought it sounded much better. So in the past year I have been practising with my band and recently gigging quite frequently and noticed my amp losing the power/volume it once had and also degrading in it's general tone. So I decided to do a complete retube. I swapped the Sovteks for some 9th Gen Chinese 12AX7's and got a new set of JJ E34L's (after much deliberation about trying the new JJ KT77's). All I can say is WOW!!!! This amp is a tone monster now. The power/volume has returned, as well as much tighter, more defined bass. The tone in general is also much improved. It's the best $150 I've spent in a little while.
I may still grab a quad of those KT77's and give them a whirl.
