Hey guys I'm changing the speakers in my 2x12 cab, as of now the speakers are 2 celestion vintage 30's. I'm going with a G12H30 and I wasn't sure if I should put in a Greenback, V30, or another G12H30 for the second one. I see that with the G12H a lot of people combine speakers. What combination would sound the best? I am playing a Les Paul with a JB in the bridge Jazz in neck through a Marshall JTM45. I want a big, tight, balanced sound.
