3) Selmer Little Giant
It's not a guitar, no, but it was Keith's first real guitar amp, and the Selmer Little Giant has a voice of all its own... you could say it has a Truvoice all of it's own, if you're the sort of person who likes amp-based puns.
The 4-watt Little Giant housed an 8-inch speaker, an EL84 power tube and an ECC83 preamp tube, giving it a swampy, fuzzy sound full of mangled mid-range dirt when fully cranked.
