They use to put case candy in, ie a hex wrench and extra springs and what not. Sometimes dealers will put in polishing clothes. There is usually a warranty card in there.
I think it all depends on where you purchase your guitar from. I purchased my JP from GC brand new (had only been hanging -high up - on the wall two weeks). I received, the EB care kit sample pack (stickers included), schematics (since my JP has piezo option), a key for the case, and trem extra springs. I was also told by the GC sales rep that I was lucky to get the signature case with the guitar....hmmm...
Im sure an instrument ordered directly from EBMM will include everything including the registry card (which mine did not come with - registered my JP online anyway, so no big deal). Hope this helps. Cheers!
sub 1: old soft case with a rope for a strap, plenty of mojo and a pamphlet on a 12 step program for Musicman addicts.
Spaceball 3000: A demand payment letter addressed to Radrock from the cable company, 25 trem springs, an unused diaper and 17 picks.
Unstained: 7 Spitfire skateboard stickers, a pack of wheel bearings, a "Pete DuBaldo for Mayor" sticker, a jar of honey stain with a letter from BP saying that if the buyer doesn't like a natural quilt, he can stain his own damn guitar and a pack of wonder wipes.
Black Cherry Burst Al: A petition to rid the world of Floyd Rose (which I refuse to sign), a bunch of thumb picks, a tax bill from King George for tea and an engraved invitation to the ALOC (which I accepted). There was also a casette tape with Albert Lee giving instructions on how to play the guitar, but the accent keeps throwing me. Something about "El Kabong". Oh....and another of those damn 12 step program fliers. I DON'T have a problem......I keep saying that.
