Thanks for the comments,
Juan-king it would be a dream to get an endorsement or commission but I suspect Martin does not need to do such things. For me it is just a real pleasure to let others see Martins work which are totally beautiful art and at the same time ultimate gigging/studio basses.
Big Red, my thinking behind no controls was very simple, I do not vary my tone controls once set I prefer to use my fingers, and as for the volume, I always turn it on full and adjust at the amp for the stage volume. So really I could do without anything.
For me the real eye opener was the Kent Armstrong humbucker. I described the sound I was trying to achieve to Martin and he relayed it to Aaron who wound the pickup. Aaron got it spot on and I have not even considered a pre, either inboard, the bass does have the cavity if needs be, or outboard.
Btw BigRedX the facing is flame sycamore, I think the same as you are having. Although the pics do not show it, the flame is outstanding and goes from the body right through the fretboard to the headstock. Martin and I tried to get a one piece flame bass and when seen in real life it really works.
Here is a picture of the fretboard which show you what I mean

If your peice of flame sycamore is anything like mine, and I am sure it is, then you are in for a real treat.
if anyone wants to see some more photos then here is a photobucket link.
