Hey guys. I got this week my first tube amp. Its a handmade 30w head. I am now going for a cab. I'd like your thoughts on some matters. I appreciate the time, and thank you in advance. I'm aiming at a 2x12, with 2 Eminence GB12, they have 50w each. Wattage wise, I'll be ok right? And what do you guys think about this speaker? I like to play a little bit of everything, from blues to black sabbath. Another thing that I am a little bit lost... My amp has two output jacks, one for 4 omhs and one for 8 omhs. I have only used the amp a little so far since I just got it, I used it on my friends 1x12 cab, which is a 8 omhs cab. So I only used my amp in the 8 omhs jack. The people here that make the cabs told me that they only have 8 omhs speakers, so for a 2x12, they would wire them in parallel, so the cab would have a IN MONO jack of 4 omhs. My question is, is there a difference in tone if it was 8 omhs, or 16 omhs? And I'm talking here about a perfect match (4 ohms amp with 4 ohms cab, 8 ohms amp with 8 ohms cab, and so on...), not a safe mismatch... Is there a difference in sound between them? Something I should worry about?
