This is considered one of the better FRFR solutions for the Axe-FX and similar modelers. Originally these were $800-900.
Having used both this and the Atomic stuff, this is better sounding (fuller, more power, and better detail). Good vocal quality too, if you do vocals.
I'm look for just $400, but interested in trades for some effects pedals, esp. stuff like the m9 or m13. But I'm pretty open to any guitar-oriented stuff.
