It's interesting how the signature market has split in two directions. It always used to be the artist's vision of their dream instrument, usually (but not always) a standard design with custom tweaks like pickups, wiring and hardware, an instrument designed to facilitate the needs and unique playing styles of established iconic musicians. Since fake wear became a popular thing, signature instruments have drifted to a point where it now also means replicas of standard instruments with no real tweaks other than imitated wear. EBMM are stroking both sides of this particular piglet, with the likes of Pino and Cliff Williams on one side and the radical designs they've built and put into production for the likes of John Myung, John Petrucci and St Vincent, among others.
Being honest, the replica instruments do little for me, particularly when you can buy actual instruments from the same era for a lot less. Getting your hands on what exceptional musicians have done to push beyond traditional designs from the previous century is far more interesting, to me at least. 6k seems crazy for this as, once you start playing it and putting your own dinks and scrapes into it, it becomes less and less Pino's and more yours, which is the opposite of what you bought it for in the first place.
