Ok...here's the skinny...which isn't good...but the PROGRAMS ARE...
Bias Amp is where you build and tweak your Amps...and it's extensive what you
can do...Pro gives you the Amp Match module, the Pro Convolver, and the
Glassy, Crunch, and Insane Amp packs....
Biax FX has all the pedals, etc...where you can build your own "pedalboards"
and integrates with Bias Amp for the best
of both worlds...obviously Pro of each being the best of each...
You also get lots of user and Artist amps, pedalboards, and presets etc...from the ToneCloud...
Currently on Sale for $179 each for Pro, or $79 Each for Standard...
Highly recommend the demos...right now...they are edging out Amp 4
and S-Gear for me...due mostly to the "Tweakability"...
S-Gear still is the "Out of the box" champion for me...
But Bias is a pretty serious threat to both S-Gear and A4...
