By the looks of the bass T-rods, these are Star/Hoshino built. Nice drums, but I am not sure Iw ould drop more than a bone on them as they are just not top of the line stencils. They are Gretsch knock off lugs and some other parts are Gretsch-like, but all in all, they are still not the high end of the Star quality. These would be after Star halted production under the Star company name and would have been built under the Hoshino moniker in order to keep cash flowing while TAMA took it's place in history. This is the short period of time after Star, while TAMA was getting up to speed in a new market, the Japanese high-end market which they brought to market.
Many people believe, erroneously, that Pearl brought Japanese drums from stencil builders to top quality drums. TAMA actually began building high quality drums rivaling, and in some cases exceeding, the quality of the very American drums they had so sought to emulate for so many years. Today, TAMA still builds some of the worlds top quality drums, right alongside Pearl and Yamaha. Actually, I think TAMA are far better built than Pearl, even though Pearl still pulls out the "World Series" or whatever they call those exotics from time to time.
TAMA does it on a daily basis with the StarPhonic Snare Drums. The woodies are among the finest sounding wood snares I have ever heard. These are built from quality woods, bubinga, birch, maple and some other exotics as well on a limited edition basis. I am certainly not anti-American, but we just are not competing in the high-end market today. I wish our drum manufacturers would wake up and smell the lacquer, but it seems we are content to rely on Korea, China and Taiwan to build our drums, and everything else we consume.
