Any guitar's compatible with GH on PC? (besides rock band guitar's)

I was wondering if there were any Guitar controllers out there that would be compatible with GH that was a viable option? I do have a working guitar controller, but, would be nice to see other aftermarket guitar's (besides rock band guitar's) that work with GH on PC.

Edit: I feel like people didn't get what I was saying. I already have a guitar hero guitar (Xplorer) for myself. I was wondering if there was other guitar's out there, not rock band or guitar hero guitars. Just OTHER branded guitar's that would work for GH on PC. I'm just curious on this as I've never really seen one. Like, you know how you have other brands like Mat Catz making PS4 controllers that work with the PS4, but it's a different controller. I saw the Riff-Rocker USB MINI Guitar controller that UKOG used on one of his recent video's. I was wondering if there was something else like that (bigger of course) that could be used for GH for PC.
