In the factory bundle, the RedWirez have more bite to them than other IRs. They're spikier in a bunch of bands. Solo'ed that can make them sound a little jarring, but they're particularly good for making your sounds poke through busy band mixes.The stock cabs itself in the AFXII are very nice today and i've been a long time fan for ML Soundlab IRs... But this makes me wanna go and see how the good old Redwirez IRs sound after all this ultra hires goodness, that we've used to.
