It's not that cut and dry I dont think. I look at it like this...
A company approached Steve (or any other endorsee) to create a pedal/amp/guitar/window scraper. At that point in time it fits his needs perfectly. After a while, needs may change. He may want a different type of sweep on the wah, a wider scraper on the window scraper, etc. So he finds something that will fit the bill. It doesn't mean what he designed before sucks all of a sudden, he is looking for something different.
Or it could be with the amps that Carvin came at him and said "We have been getting lots of requests for an amp that has a specific set of requirements, we created a design that is similar with the Mini V3, but we want to make a Legacy version as well, would you care to help us work on it?" Steve may not have had a need since the L1 still works great for him, but he did help design it for a certain set of needs and he put his name on it.
It's the same with guitars. Satch for example has had a plethora of models with Ibanez, he may not play the first one he ever designed all the time. He may not play the new model all the time. People switch things up depending on what talks to him at that moment.
Paul Gilbert has the Fireman guitar but he stills rocks the old PGs as well live.
Just because they helped design it and their name is on it, doesn't mean they use it exclusively. I'm sure the Carroll Shelby still drove a Mustang (or other car) once in a while.
Yes but Joe and the rest do use their stuff. Its not hard to find examples of it.
I didn't say he had to use the L3 exclusively. It does not appear to me he is using it all. And if
he is not, I said its fair to question why he is not and it is.
He spoke about how he didn't like the L2 as much so channels 1+2 were put back exactly
like the L1. He further went on about how he felt limited by the 2 channel design of the L1, hence the 3rd channel. He further went on to say he no longer needed a boost pedal etc (thrilling Ibanez to no end I am sure). That sure sounds like design changes HE
wanted, not Carvin's user base. If those are things he really wanted one would think he would be using them.
Putting them on top of the rack were everyone can plainly see they are not even plugged in as backups speaks volumes to people who are not die hard Vai fans. They didn't even try to make it look used. Given how cheaply L1's be purchased used why would anyone buy the L3 after seeing that?
Maybe he is having tech problems with them. Mine has been back to the shop at Carvins request already for a repair. I never said he didn't have a good reason. I said its fair, given the circumstances, to question it in the absence of information from anyone who might actually know.
