I too am brand new here, and I too got the fever for a Silverburst bass.
I have been putting in some time & effort into discovery with this sucker.
Little back story, I saw the Silverburst on MusiciansFriend when it was released, and all of a sudden one day I saw a different picture of the Silverburst TBird w/ the chrome p/u & black p/guard. I was on the horn with mf right away!
They told me that they "couldn't explain the picture" LOL, because the one they carry DOESN'T look like that! Low & behold, the picture was GONE the following day.
I have scoured the web since & recently landed on a picture of this fabled bass (FINALLY!) on Gibson's website (not even Epi's) so i dug deeper again.
I will share my findings:
As far as I know, and it seems you guys have established, their are 2 diff't Epi Silverburst TBirds.
-Musiciansfriend carries & sells the "base" model, so-to-speak.
the one with the un-covered p/u & white p/guard. Your standard run o' the mill Epi TBird.
-THE OTHER is the Ltd Edition one, carried by approved Epi retailers.
So I took the road of contacting my local retailer, and he provided with me with this info.
(*accuracy TBD)
-This bass is brand spankin' new. So new that Epi doesn't list on their website, only @ Gibson's (I disagree with his reason, I think it's listed @ Gibson b/c it's a Ltd Edition, but...) His vendor assured him they are coming around sooner then later & he was going to get back to me on the basses "transit time."
So my acessment is the bass is GOING to be out there to be had, obv. Likely in 2010. Perhaps MF will pick up a handful of them ala the Gibson Guitar of the week models, but it's definitely something that you can visit w/ a local "approved" retailer and hope they do the dirty work for you.
Sorry to be long winded on my 1st post. But I do hope this info helps out, even a lil.
Thanks guys!
