To clarify, and thanks McNic...he is correct. These are superb instruments, my comment is not one of disdain, from a personal position, just a "public perception" issue of most Japanese made drums from the 60s-80s, that they are inferior. TAMA has ALWAYS made decent gear, as well as Yamaha. Both are top notch, with Yamaha taking the slight edge in real time quality, but overwhelmingly higher resale potential. Pearl...eh...they are the Chrysler of Japanese drums, IMHO. They build good gear, but far too much and the resale reflects it. How many Forum and Import kits can you possibly stuff into the music stores' inventory??? And you better wait to buy your Pearls until the end of the lifecycle on that particular run of model numbers so you don't get hosed too badly.....But who am I kidding, buying a Pearl is like buying a Kia, you know you lost half the price as soon as the credit card machine spits out the reciept.
Actually, "public perception" of Tama drums from the 80's is of top quality thanks to Peart, Copeland and Phillips. The Superstars from the 80's are sought after, 6 ply, 9mm birch shells. Heavy but still sound great and some of the best finishes of the time. Theres good demand for them. The selling value has dropped a little over the last year. Usually you will see these parted out for the most money and ease of shipping but in absolutely mint condition drums values are around:
bass drums 22-24" $150-200 ( hard to ship. 20 and 18 inch bass drums are much more in value)
common sized double headed toms (12-13-14) $100-150 (standard size drums are on the higher end of the scale) Concert toms are about half those prices. The 15 inch double headed tom is a little more as its a little more uncommon, maybe $150-175.
18 floor tom $175-200
20 inch floor tom is $300+ (hard to find)
The snare could be $250-350 depending on which model and features. There were several Super Mahogany snare set ups. Some with rollers some without.
If they have many scratches expect less money. Missing original snare or muffler will reduce the price.
The smaller double headed toms are desirable. The 10 inch can go for $200, the 8 inch $250+ in either 8 inch or 9 inch depths. The concert tom 6 could be around $175+, 8 maybe $130.
These are what they were selling for in the last year as I have been buying and selling a bunch to get all the sizes I wanted to finish my set. Prices can and will change according to what people will pay for, economic concerns, whos looking on any day, how often you sell on ebay, buyer confidence in the seller, your quality of pictures and descriptions, etc.........
If you live close and don't feel like shipping I might be interested in the set if its in good shape.
