Yeah, it does suck, and now that you mention it, it would have been interesting to hear him do that. I wonder if he's even aware of the Transcale concept, as the Synapse baritone does indeed work under the same principle. If he could have get Ned to make him a one-off that goes down to Bb or C from the standard E/25.5" scale (as those seem to be the two he most clicked with) he could play all that material again!
Oh, I just checked...the C tuned one is 34", the Bb one is 36", and the A one was 38".
Just found these pics of his double-neck baritone/regular guitars. Looks like it's E on the bottom and C on the top, judging by the number of frets.
Damn, I wanna play my baritone 6 now!
