I'm thinking about putting in a new speaker and tubes in my newly acquired Model II. I don't get enough low end and the tone is a little bright for my tastes (especially with singles). What's the difference between alnico and ceramic speakers? Right now I'm mainly looking at Weber speakers--these specifically: 10A100 - $85 AlNiCo Signature 10 - $50 10F100 - $75 (Ceramic) Would it be worth it to spring for the "vintage series" of the same speaker (10A100) or the ceramic version (10F100)? I've heard there isn't really any difference between alnico and ceramic speakers and the tone has more to do with the quality of the materials. So would it make more sense to spend an extra $25 and go for the Vintage ceramic 10" speaker(10F100) rather than the Alnico Sig10? I'm assuming the Vintage series uses higher quality materials? Or no? As for the tubes, I want to get tubes that have a fuller bottom end with a tighter sweeter top end that isn't too bright and a balanced midrange. I'd also like to get relatively early breakup that breaks-up into fat, warm distortion. It doesn't need to get much distortion as I could always throw a pedal in there if I wanted more. Another Kalamazoo owner recommened old GE tubes or something. I'd really prefer not to spend more than $20 per tube. Any suggestions?
