I was watching Phil Lesh & Friends webcast from the Rothbury festival on Sunday night and saw (also heard) Phil playing a very radical looking black 6 string bass. Looks like something that Esh might make - somewhat akin to their Poseiden bass.
Here's a link from flickr that a phan took:

It's got blue led fretboard markers, looks like one massive brick of a pickup, and an interesting bit for a tailpiece, where the string seems to pass over a bridge (piezo pickup?), and extends from some distance to the tail.
My guess would be it's a fair bit lighter that his regular mammoth Q6.
Tonally, sounded less clicky with his picking and more smooth than the Q6 - almost a throwback to warmth of the 70s. Though no doubt there's some tweaking he can do with the controls on it, cause he definitely had some different things going on sound wise.
Any ideas ?
