Hey guys, I need some opinions aside from those who chimed in on SS.org...which it seems only 2 members here would have (Ken and Mike). So here's the situation :
Mesa Mark IIB - $400 + shipping
It's a rackmount unit and the clothe part of the head got totally fucked up so it's no longer on there...at all, which is most likely which this is going for so cheap. From what I've heard the IIB isn't a really hi-gain amp and apparently can't get close to modern metal Mesa tones like Lamb of God (Mark IV's); not to mention this also doesn't have the graphic EQ on-board which would require a seperate bedal for.
Mesa Nomad 100W - $500 + shipping
Decent shape, seen it's days kind of thing, with the only real problem being a bit torn to shit and the knobs looking fairly old/out of place. This DOES have the signature Mesa 3 channel setup and the on-board EQ and for $500 as a head it seems like a hell of a steal since the Nomad 45 combos go for about $200-$250 more.
Both of these will be running through an Avatar 2x12 with Celestion V30's
I don't have any experience with a IIB so I'm no help to you there... But, I will say that while I no longer own a Nomad, it's still one of (if not THE) most versatile Mesas (and, by extension, tube amps) I've ever played. The inclusion of the 5-band EQ on the 100 should only make it more absurdly flexible. If you're into the Mark-sort of sound, then you'll probably dig this, though Channel 3 Modern can get quite close to Recto territory.
