What a cool idea! The MIMF/Musical Instrument Makers Forum members are planning to collaboratively make a bass in order to raise money for the Forum/site. Members will donate their materials and labor. The way they see doing it is shipping it among the selected volunteering members for each component. They want it to be made as much as possible by the members, (there is some real talent in the membership). This includes custom pickups made by a member, inlay, the preamp, the neck-through-body, the bridge, and the case. (I'm a member, but don't let that worry you - Rick Turner is, too). The bridge is supposed to accommodate piezos. Tuners and some electronic parts will be made by external sources. The wood has been donated by a member, which includes a bookmatched myrtlewood burl top plate. When completed, they will sell it at public auction. The MIMF newsletter says, "...want to stress that we need this bass to turn out absolutely top notch. It will represent...our best work to the world." PLUS, if this one goes well, they will do more of these. The plans and a picture of the board for the top, (mercy!), can be seen if you scroll down the page at - http://www.mimf.com/cgi-bin/WebX?14@@.ee751e5/0 Yes, it is a 4-string.
