Anyone using one of these amps? I did a quick search and there were some nice hits and good reviews. Some of the early reviews on HC were less than positive (but less than informative as well :NUTS) so I'd like to get current or previous owners experiences with this amp. I guess these are under the radar a little bit. The one in question is actually a 2x12 (might be heavy) which is not listed as an option on Rob's site anymore. I didn't realize these run 6v6's (can you install 6L6 for more power/clean headroom?) which is pretty interesting. Without the manual in hand I'm trying to glean more information about the clean channel / dirty channel and then boosting? and jumpering? Sounds like many tones are available in this beast.
