I recently purchased a vintage Musicmaster. It's pretty much all set up for me w/ NOS RCA tubes. I love the tone of it, but I think I can make it sound better with a speaker upgrade. It has a no name ceramic in it, and it's a bit too punchy for my taste, so I'm looking for a good alnico replacement. I'm a huge fan of modern Slowhand tone, so something that will give me that sort of characteristic would be ideal! I play mostly blues/rock ala Clapton and the Stones. I have been considering a Weber signature 12S. Any suggestions?
