My guitarist and drummer's roomate (who's also a good friend of mine) has a Black Face that I play through every time I'm there. He uses it for guitar through a 212 Cordovox guitar cab as his practice set up in the living room (he has a Mesa triple rec for shows, I plug my bass in and it just sounds so wonderful). I fell in love with this amp! I had the oppertunity to pick up a closet classic black face with matching 215 cab for $500 locally, put it this way... I kick myself for not picking it up everytime I play my buddies. He payed a bit more ($750) for his head alone, and I seem to see them go in the $500 range quite often. I'm going to pick one of these up for a home practice head after I re-work my live rig and have some spare, spare scratch to throw down.
Let me add that I take the head down stairs (to where my band and his band practice (let's just say there's way to much awseome equipment to fiddle with in that basement) and plug it into my henry the 8x8 or Trynor 215 (even Marshal 1960a) and it sounds wonderful, albeit not enough power to produce any clean tones capable of keeping up with the band, but wonderful none the less.
