Since when did the LP Sig have a maho neck? All the ones I have seen have a three piece maple neck and sound like it too.
Don't shoot the messenger, that's official Gibby lit not my word. My understanding (as implied in my post) was that these were the prototype specs (note the pup - it appears to be a cream coloured, possibly gold like the L6S, oval shaped Triumph pup, and is described as such verbally vs the square LPSig/Cassidy pup we all know from the production models... also dual output jacks, I assume for seperate Hi and Lo Z outs) and that these specs changed at some point before production began or not very long into it, though I don't think any of us have ever seen one (other than Rob's fabulous recreation, which was inspired by the discovery of that pic way back in the Pit days IIRC... also I think you said the same thing back then re the neck).
This (the spec change, at least as regards the neck, God only knows why they changed the pup - very much unlike Gibson to design something from scratch when there's a suitable component in the parts drawer) was likely because at the time they were changing all basses from shorty maho necks to for maple long scales anyway (see the EB0 and 3 of that period, as well as the recently introduced EB0/3L and later EB4L which had no shorty version - EB0s changed to maple in 72, LPSig was released in 73, EB4L in 72, and first production long scale in 70). Frankly, I wish they never did, hence my Homer Simpson impression.
... so yeah, I want a maho shorty neck LPSig with Triumph pup and a deeper body. Not happening even if I could afford it.
