While it's not technically a modeling amp, I'm currently playing through a Pritchard Sword of Satori that has several voices. It's a solid state amp unlike any other out there. Eric Pritchard (worked at PRS when it first started out designing amps and manufacturing machines for them) has a unique system with multiple patents. It is analog solid state and I can get voicings of Fender, Marshall, Vox, Mesa lead, and several others, including an acoustic amp voice that, along with the two horns that I control with a footswitch, gives an excellent acoustic amp tone. I must admit I was extremely prejudiced against solid state and modeling until I ran across this Pritchard. It's nothing short of incredible. At the last Northern Cali Alembic gathering, I had it set up on one side of the drums while on the other was a Marshall double stack. The Pritchard (about 18 by 17) looked like a little toy in comparison, but after we were done, the Marshall guy came over to me to tell me how great my Pritchard sounded!
As for the coffin guitar, it would be great for a cover of Monster Mash at a Halloween gig, or for backing Screamin' Jay Hawkins. Otherwise, why?
