An early 2000's Squier Bullet body painted silver, a cheap Memphis copy neck w/ reshaped headstock, and a pickup from a 60's or 70's Kent guitar mounted in a steel pickguard I made out of an old computer case and it strung up w/ .013's in open E. Weird, but a great slide guitar.
I also wax potted the pickup before installing it and it has zero microphonics despite the metal pickguard; I had a bad experience with a gold anodized guard doing that in the past, so I'm glad this doesn't. I held it two inches from the speakers on my amp and it didn't squeal. Mission: accomplished. It's a loud beast despite its 6.4k output reading and rings like crazy acoustically, which is strange since the body is super thin, probably 1 1/4" thick. Might have to do with the single 500k pot. I mounted the pickup in a goofy place on purpose, too, with the poles lining up somewhere between the middle and bridge positions of a normal Strat. One of my other slide guitars is a regular Strat so I wanted to try something different. It was fun and free so what the hay.
