It's a mean little head, capable of delicious boutique EL84 tones from non-pristine clean up to ripping tube overdrive where every note shines through. It takes pedals very well (loves a Fulltone Fulldrive) though would probably ideally suit the volume knob riding player best as a plug and play solution. Tonally it's ACDCesque so I guess you could say vintage Marshall (taking into account it's 18w, not 100w).
I think this video showcases its tone very well:

This is the video of the non-reverb model but the one I am selling has the additional reverb. In theory this makes the amp less aggressive but trust me, I like my amps screaming and this thing did the business.
Reason I will be selling is my guitarist needs a louder amp than this to match the crushing power of my 65amps Marquee 35w rig, but if I was looking for a great amp for rehearsal, reasonable home volume and playing pubs with a 57 in front of it, this would be it.
It looks exactly like this, and is 100% mint.

It comes with a $550 roadcase by Janal. http://www.cases.tv/
I'll be looking for $2200 for the head and roadcase. This amp is what many players are seeking - a tube amp that is loud enough for almost all applications and yet quiet enough to rock at home. PM me if interested.
