I've managed to try some CS fenders, Groshes, Tylers, Suhrs, etc. since there is a shop here that sells boutique guitars(they're not an official dealer of any brand though, they more like very good condition 2nd hand units) but never did they have an Esquire which is quite a common phenomenon among guitar shops.
But honestly, a build like your La Cabronita looks a lot more customized(even with its simple motif) and inspiring than an official custom shop. I could imagine the thrill of building one guitar that's just exactly how you want it. :)
Btw, do you have a clip of it? I haven't played a guitar with filtertrons yet. I only heard them extensively on some Brian Setzer records.
