Although the serial number got accidentally erased (I have pics of it), it can be easily identified as a prototype because they had a headstock approximately 1/2" longer than the regular production models (you can confirm this by emailing Reverend). All other specs are as any regular Roundhouse HB-FM.
Guitar is in great condition, barely played, only has some very slight hazing on the pickguard due to playing, and a hairline, long scratch on the back, barely noticeable. Guitar plays great, sounds great, low action, very solid--I just have too many Reverends already, so she gets little play time.
The tone is pretty LP-ish, a bit more cutting, even more so if you dial the sound using Reverend's unique bass contour control, which removes bass frequencies from the sound.
I can snap more pics upon request...
