Did or would you go with el34's or 6l6's for the power tubes and why? or 6v6's for that matter.
No 6V6s, too much current for them.
I choose 6L6GC over Nik's suggestion, even if I do prefer EL34s to them. Nik built the amp with 6L6, so the tweaks were made with them. Generally speaking, 6L6 bigger and more defined bass response, but less and thinner mids and distortion "flavour" is thinner, modern, while EL34 give you a not so good bass response but bigger and more pleasant mids and the distortion is much more harmonically rich. This is just my experience. I was 6L6 guy, now EL34.
For the fellas who did the reviews< sounds like you are comparing the Overtone to more of a TW sound that what we generally look to Dumble for (LC, RF).
Are you really not able to coax those sounds out of the amp?
I was thinking the same, I know it's strange, but what I can tell you? I can't get that tones and I'm near to Marshall grind, with strats and humbuckers too. As I said sunday my amp will be played by some guitarists, I'll report their settings and tones.
Thanks for the info. very informative. I have been thinking about ordering another amp, so I am gathering as much info as I can. We'll all be looking forward to the additional feedback from you on those other guitarists.
