I've been researching and tracking 8000/9000 kits the past year....especially from 1977-1981. One of them popped up last summer and for some reason the seller disappeared. But, another one appeared last week and I was lucky to be the first to contact the seller. Picked it up Thursday....finished cleaning the drums last night. Now waiting on new heads for the snare drum as both had punctures. Too bad since the reso head was an original Yamaha inked head. The 12 and 16 toms also had original Remo white coated ambassador batter heads on them. Standard sized YD 9000D plus 14x5.5 "dark" real wood SD755D snare with original snare wires and tension tape. The Kit came with some original 9000 Yamaha gear: single post - strap drive - kick pedal, one straight cymbal stand (extends up to nearly 6 ft), snare stand, and hi hat stand. Other hardware was Pacific. Quirk #1`is the hi hat stand is labeled Premier...and Yamaha didn't own them until 1987-1992 or so....hence not original to the kit. But it's a Yamaha 9000 style stand in all respects except for the Premier foot pedal and the Premier decal. I suspect it's a late 1980's stand but still a 9000 with the notched adjusting tension wheel. To fill in the cymbal stand gaps, I already found a pair of gold label 9000 "mushroom foot" stands to fill out the kit. Quirk #2 is the May 1981 SD 755D snare going with a 9000 kit that was made around January 1980....all other drums date to within a month of that. Did this kit sit in a music store for a year before it was purchased, and then a 1981 SD755 was added to it upon sale? Even Yamaha's own catalog had a 700 series snare married to a 9000 kit in one of their suggested popular lineups. If you didn't want the bulkier super sensitive snare drum...you got the 700 series...which was identical except for the SS mechanisms. We'll never know. Quirk #3 is that the 12" tom is badged as a TT-912DA...not D like the 13,16,22. Very odd as the DA badge signifies a mixed birch/camelia shell...basically a 7000 shell of that era. It's birth date was only one month earlier than the other drums which fits. It was probably stamped wrong as the bearing edges look identical to the other toms. All the edges are very clean and smooth. First photo was taken after I cleaned and stacked them. The second photo was the seller's. 2003 (early style) Zildjian ZBT's were the cymbal pack for the kit. The kit was purchased by the owner for his son's band. They mostly stayed at home but occasionally went to another band mate's house. The son played guitar. So nice of the dad to supply these drums for the group.
