I think they were called "Resonators" or something. Yeah, I played a light PURPLE kit back in the late 70's. They sounded okay....nothing to write home about. They were SUPER heavy. I hated them for that reason.

You can research videos of live performances from name (and other) drummers- one thing tho--- the inner liner was easily pried out- so you can't see (if it's in there or not)- I saw one set in person. Without the liner they were same as the other top line they had at the time. Look up Charlie Persip and Stan Getz drummer can't think* of his name....Philly Joe Jones lots of later videos playing Premier.

* Victor Lewis-

(solo below- resonators..well floor tom still has thin strip label below badge may have fell off small tom) Top end Premiers (after the late 60s metric mostly birch period) were soft mahogany thin 3 ply shells with beech rings- very dark tone sounding drums. later- ( the top line 1990s -Genista birch and Signia-maple- a total redesign- a company rebirth- under part Yamaha ownership era- were a totally different kettle of fish - from the 70s drums)
