Yeah, that 77 slant originally had all Blackbacks but 2 developed buzzes as the note decayed so the V30's went in. When it was all Blackback the tone was brighter, a tad looser, and yes, slightly less mids, though I wouldn't call it scooped. Amazing speakers for late 70's ACDC, but also did Zep tones really well. Would love to get another cab loaded with them. The reissue Greenbacks do have some wood to the tone but nowhere near the 68 Greenbacks. My fave cab at the moment is the 77 Blackback /V30 cab. It's a tad less modern sounding than the 1960ax but tighter and punchier than the 68. It is bright and mid focused but not harsh or boomy, and in any case, that's what I find works for me in a band setting. Edit: Regarding those V30s in the 77 slant, they were originally in a friends Blackstar open back 2x12.....probably not as good quality as the Artisan, but a Blackstar nonetheless. Neither of us thought it was a good sounding cab....way too middy/dark/loose. I bought them off him to help him out and put them in an older 1960ax with 2 English Greenbacks. Liked it better than all Greenbacks but when I decided my newer 1960ax was a better sounding cab I put the Greenies back in and sold it. Now they're in the 77 and I'm stoked. So the lesson is, the cab itself plays a big part. Also, I've played those V30's alot over the last couple of years......maybe they just needed to break in.
