This is in response to the previous thread regarding the number of Zendrums there are. There is a short answer and there is a loooooooong answer as well (of course!). I have been working for a very long and complicated time to get as close as possible to the exact number. So here you go:
Short answer: As of now, mid-July 2007...the number of Zendrums in the world is 969.
This is all the Zendrums made since our beginning in 1993 starting with the datawheel Z1's, including an estimated number of 20 (will explain that in the long answer), also including the plastic ZP's and Muses made in 1997, plus the current orders we are working on. By the end of this year, 2007, there will be >1000 Zendrums in the world.
Long answer: With help from our subassembly person/office assistant (thank you Nancy!!), who happens to have just the same OCD that I do about data and numbers, I have very recently finished a lengthy and complicated project of sorting and cross-referencing all the Zendrum serial numbers and related information to re-establish the Zendrum serial number data base. We have sorted through every piece of paper and every page of numbers we have found in the archives, every entry in the current Zendrum Techno-Tribe contact list, working our way forward from 1993. In recent years, since early 2000, we have used a definitive system for recording the serial numbers with every order both in paper files as well as computer files. Before then all the serial numbers were recorded on paper.
David Haney has explained that in 1993 and 1994 there were ~20 of the first Zendrums he and Kim Daniel made that don't have serial numbers...this is the estimated 20 Zendrums I mentioned above. This number includes several original prototypes along with: original Zendrum Z1's (the original long tailpiece model) such as the one we took to show Peter Gabriel in 1993, then the very first Zendrum sent out into the world to Perth Australia to meet up with Manu Katche on the Peter Gabriel "US" World Tour; some of the other very first Z1's such as David's Zebrawood known as #001, then a Birdseye/Purpleheart known as #002 made for Billy Cobham, then Kim's Lacewood known as #003, then Purpleheart #004 for Michael Bastido, a musician in Atlanta who used to work with us...this is one of the first with the newer shape and the only solid Purpleheart Zendrum ever made; others including the first two ever sold (at Summer NAMM 1994 in Nashville)...1st one sold to Leon Russell, 2nd one to Oliver Warren who is the drummer on Roy Orbison's "Pretty Woman"; two prototypes made for Futureman; then one which was sent over to Real World Studios; Kim's Yellow Pearl Zendrum which was photographed for a NAMM brochure and for print ads in Modern Drummer Magazine; and a few others. Some of those first ~20 Zendrums are hanging on the wall here in the office, signed by the artist and returned to us in exchange for a newer Zendrum, but we have lost track of a few of them.
By late 1994, then 1995 and early 1996 the serial number for each Zendrum was printed on two small white stickers, one on the outside of the backplate and one on the inside of the backplate. Those serial numbers started at #100450. Then in late 1996 the current 3.0 circuit board was introduced and from then on each circuit board has had a serial number imbedded on a chip. Until early 2000 each of those serial numbers was recorded on paper in a list with the owner's name and the date.
In late 1999 when we moved out of the Zendrum office and manufacturing space at 2299 Peachtree Road in downtown Atlanta, we moved everything to two locations...the office went to one place and the shop went to another. We are a very small number of people and we were all working as hard as we could to get it all done (just as we still are!!!), but during the move some boxes of crucial files were misidentified, misdirected and ended up in storage. In one of these boxes were the hard copies of the serial numbers lists along with hard copies of all the orders for several years. To complicate things even further the office computer crashed right before the move (naturally!) and we lost the contact list and data base onboard. When we did retrieve the boxes of files and the serial numbers lists, I started sorting through stacks and stacks of paper, cross-referencing all the numbers and other information, methodically re-establishing the Zendrum data base.
David has told me that until now when he was asked how many Zendrums there were out in the world, he didn't know the exact number, and the number he guessed was an estimate that also included some of those early prototypes he and Kim had made as well as quite a large number of Zendrum bodies that were carved and painted but never built and sold because he (Inspector 109) and Kim didn't pass the finishes. But the number I have sorted it all down to now is the actual number of Zendrums built and tested by Inspector 109 and sent out into the world (or about to be!). We realize that our Zendrum owner list is not completely accurate now, as of course we have lost contact with some earlier Zendrummers and others have sold their Zendrums on to people who haven't needed to contact us. But even though all the names may not be current and accurate, this number is.
Okay, all this may be WAY more than you wanted to know about Zendrum, but here it is. Since I worked so long to get to that number, I'm glad someone wants to know it...thanks for asking!
