Fender Steel King?

[tabcantab]

Anybody ever messed with one of these (especially for non-steel guitar purposes)? I've started playing keys with a couple of loud guitarists and need to keep up on volume, and somebody has one of these listed on local craigslist for not-that-expensive, but I've not come across one before.

I'm intrigued by the 15" speaker, wattage, spring reverb, and Fender-ness, but curious about the EQ and how good the reverb sounds. I don't know much about what steel guitar players look for in an amp, so it's tough to say how well it'd translate to my uses, but loud & clean is a good starting point.
