Guys, I know where I'm going with my gear, currently with a few GK pieces, a fearful build in my future. That leaves the heaviest pieces in the load in 2 twin reverbs that both guitarists continue to love, 85-100lbs depending on the year built. Both of them are 55ish. Another loves his Marshall, but he's mid 40s, go figure! What kind of heads have similar sound and who's making LW cabs for guitarists? Are the fEARful usable for them also?
