PwrCabs vs IRs
PwrCabs are NOT simple IRs. Similarly to Virgo, each PwrCab is made up of 10 harmonics x 30 levels = 300 different FIR impulses, giving you a dynamic, deep, “living” tone. It represents a completely different solution from the usual IIR based plugins and the most accurate existing reproduction of the final stages of a regular guitar recording chain.
