Hand made by Patrick Koopman (Stevie Vai's guitar tech) in the Netherlands. Build cost was £1800. I acquired it in a trade with Aero71 whom incidentally, is a total gent. 3.9 kilos, 34" Scale, 5 piece maple/wenge graphite reinforced neck, 45mm nut, Ash body, Bartolini 72MV5K splitable dual coil pickup, front coil, back coil, series, parallel settings. Seymour Duncan STC-3M3 preamp, with "Slap setting " via the pulling out of the volume pot. light weight Schaller carbon fibre/aluminium tuners, ABM Bridge. The colour is changeable, it looks like claret/red wine, but it also looks like candy apple red depending on the light. On stage it looks amazing. There was a minor issue with the string tree which is now rectified, the original string tree pulled out when I tried the bass with flat wounds, so I replaced it with a different type of string tree and all is OK, the original holes have been filled with resin, as can be see in the photos, I will send the original string retainer with the bass so it can be reinstalled if required. The bass can now cope with flatwounds no problem.
It plays perfectly, and there is a small bruise to the finish on the body, near the lower horn but the paint/finish is not damaged. It is just an indentation which is difficult to photograph . There are no electrical crackles. The knobs are smooth running with a nice "greasy' resistance.
I think this bass is unique, a while ago I contacted Mr Koopman to ask for build details about this bass, but I forgot to ask him if this was the case. There is certainly no other examples on the Internet that I can find. He has a website, take a look.
More details can be sent if required. Bye for now.
