...Vai had chosen to go with Tom Anderson or Jackson instead of Ibanez.
As we all know, Anderson had given him a guitar in hopes that he would endorse their guitars. Vai, on record, says the the TA was a very nice guitar, but had too much bottom end. He did, however, use that guitar on a few DLR recordings and toured a bit with it.
He also had a few Jacksons laying around. If you recall, a few of them (possibly his faves) were stolen at one point. If they hadn't have been stolen, would Vai still be playing Jacksons today? A possibility.
What if Ibanez had chosen something slightly different to give to Vai, and what if Anderson had chosen to do just a few things differently. What if Vai liked the Anderson more and decided to endorse them? What if Vai chose Jackson, who were already making 24 fret superstrats at the time.
Would we all be playing Andersons or Jacksons? Would Anderson eventually mass produce lower end models (RG) that would appeal more to people wallets? Would either of them hold the leverage that Ibanez does today? Would KoRn be playing Anderson 7 strings? Would Limp Bizkit be playing Jackson 7 strings?
Without the JEM or the RG, where would Ibanez be? Dead and buried? Would they still have Satch, Petrucci, or Reb? Would they have gone back to the lawsuit models and turned into an "alternative" guitar company in the mid 90's?
I leave you to ponder this...
