I also remember when Kustom introduced the "rolled & pleated" amps for rock bands...why do you never hear of them anymore? 'Cuz as cool as they looked, the sound sucked!
A drummer I know picks up old equipment at flea markets & the like, & he has an old rolled & Pleated speaker cab that I thought was gold metal flake (there's another old term I don't hear much anymore) until he lifted the amp head up to expose the top, which was white...seems it was used in a club for 20 yrs, & the smoke residue had impregnated the vinyl with a rich golden brown color...
don't know why I felt I had to waste everybody's time with that story...
