Let's put it this way: I don't think Epi calls a production halt on reg TBirds if they run out on alder, but still have maho lying around!
If I play my Epi "Snowwhite" TB and the Nikki Sixx model side by side, the latter one does sound deeper, blurrier and warmer with less attack, no matter what the pup combination. Mind you, the pups on the Blackbird are closer to the neck and of course they're "DeepSixx" ones ...
