This year saw the release of Trevor's new signature model guitar from Washburn, the PXM-TR2/TR20. It is part of Washburn's Parallaxe series of electric guitars, built for the modern shredder. But as long-time fans know, over 20 years ago Trevor also had a signature model which was manufactured by Westone-Alvarez, and he endorsed both the Pantera electric as well as the Yairi acoustic beginning in 1986. Jon Anderson also had an endorsement deal for the Yairi acoustic, beginning in 1979, and I would posit that is how Trevor came to be introduced to the brand, but that's just my speculation.
There are plenty of resources online for information regarding the Westone-Alvarez models which Trevor utilized and endorsed, including The Westone Forums site where there are more than a few Rabin Rabinite fanboys available for such discussion. And of course the Star Licks video which is all about guitars and gear, technique and tenacity (and Trevor is wearing one of his greatest outfits ever); a must-have for any fan's collection, readily available on DVD from various sellers on eBay.
In the video (produced in 1992), Trevor proclaims his deep and abiding love for his "baby" of the moment:
Here is a look at the signature model and its variants as featured in one of the Westone brochures, I believe this was from 1991 or '92:
From the fan/collector's perspective, what I desire is to pay visual tribute with the various endorsement ads which feature Trevor - he also officially endorsed D'Addario strings and Ampeg amps - starting with the three main ads for Westone-Alvarez.
In this ad Trevor is pictured with the Westone Pantera.

This ad was photographed on the set of the video shoot for "Something To Hold On To."

Here's another ad noting Trevor as an official endorser.

There were also three ads for Yairi, the first two are standard advertising format for the brand, there are also other versions with different guitarists pictured.
