1) I typically run my amp at 1/2 power for shows. I can't remember the wattage on the vintage 30, but I'm pretty sure the G12H30 is 30 watts....been fine, but from what I see the Scumbacks are the same price for 30 or 65 watts, so I guess I should just get the 65 watts to be safe?
2) The 2x12 is currently wired in parallel, both speakers are 16 ohms, so it makes an 8 ohm cab. If I get two 16 ohm Scumbacks, would it be ok to just switch out the speakers? Seems like it should be but I figured I'd ask...
3) Also, wired this way (in parallel), from what I understand: The wattage from the 2 speakers is added. So, two 30 watt speakers wired in parallel equals 60 watts handling for the cab, correct? This would be enough for how I run my amp, the JTM45 puts out in the 50's when dimed, which I never do. Typically run it at the 1/2, which puts out in the 30's....so a 60 watt cab would be fine. (which I guess is what I'm doing now lol). Would you say there would be any tonal difference in getting the two 30 watts vs the two 65 watts?
4) I use a Fender Strat and a Gibson SG, so I've got both the single coil and humbucker options....maybe a mix, or what would you recommend?
Lol, sry for so many questions lol....like with the tubes I'm still learning about this stuff

Btw I've been very happy with the tubes from tubetramp, I'll have to figure out a way to get some audio on here
Thanks!
