Actually it doesn't appear to be a close-spaced 7 at all. Joe C. is saying that the fingerboard is 4-1/2" wide. That's about 1/2" wider than my Fodera Anthony Jackson Contrabass 6, a very wide bass. Here's the only mention of it in the actual JT interview:
I don't know if Joe C. is still around or if Jamaaladeen can verify this. Or if Beaver ever got the info he requested.
I'm just relaying what's in the First Bass magazine that I received way back when
Jamaaladeen Tacuma: Well, this instrument is going to allow me to come up with some new things.
Sometimes an instrument can be a breakthrough in creating new sounds, new concepts. Sometimes an instrument can do that. Well, this instrument in particular with the combination of the stereo and how you can play it in the high register and also in the low register the combination of all that can become interesting to the ear.. So just based on that ya know I like to be very current.
Joe Campagna: Well, this is definitely the world's first seven electric string bass. They may have made a seven string upright a couple of hundred years ago or so, but I don't know that for sure. You got used to that 4-1/2" wide fingerboard pretty damn quick. Did you ever play upright? How long have you been playing bass?
