I feel the exact same way with respect to Randy. I have no idea why his tone wasn’t great, not my problem lol. I don’t have any secret. Most of my amps through a quad of 417C’s or 417B’s (much better) sound amazing. I will say I didn’t like the 417H’s as much. Not sure if Randy used that version or not. I don’t pay attention to what gear other guy’s used. I just try everything I can and see what I like most
Altec’s are a specific flavor that’s very different from celestions as are JBL’s; less mids, more extended lows and highs (much sharper), so maybe some guy’s ears don’t like that change, but my 2 cents would be to keep an open mind because the tone is so much more 3D/complex than any Celestion IME other than ‘60’s Alnico Blues/Silvers and pulsonic greenbacks. The other celestions imo are not in the same league in having a 3D/complex/nuanced tonal quality or feel. Most celestions sound cardboardy and bland when compared to them, but celestions do have the most pleasing mids IME
