Thanks for the info, Myles.
And just so you know, it would be an open-back cab to be sure, or at least a "divided" 4 x 12" where 1/2 would be closed-back, and 1/2 would be open-back.
The more I get to hear amps and cabs in person, the more I come to realize that I prefer the sound of open-backed 2 x 12" combos...and that for me, nothing beats a good "dirty-clean" coming through a pair of Blues.
And thanks for the tip on where to get a good EF86.
cheers,
