Delay block

The AFXII adds improvements to the Delay block: a two-band parametric EQ for the wet signal with low-cut and high-cut with adjustable slopes for the cut filters. The EQ stuff is on a separate GUI page with a graphical display. Source

Delay blocks now have a master feedback that goes to 200% for oscillating delay effects. Source

The tape delays model the preamp too. Source

Matman: "Axe-Fx II leaves the Ultra in the dust for delay flexibility. ALL your sounds are in here. Bit reduction. 4-band parametric EQ in the loop Hi and Low Cut... 12/24/48 db slope... Q control. 2 mid bands with selectable Q, gain, freq. HOLD switch. Master feedback goes over 100%. 60+ different tempo settings. Better TIME parameter resolution. Plus all the original flexibility of the Ultra/Standard." Source
