Only tried 5 or so far, no noticeable cpu hit. With it's drive/preamp feature it's probably similar to REDD.
Need to try it more material but so far am pleased. Briefly on my Drm buss with BFD3/ VBC RED; clean & punchy.
Got a decent sound using it on my Jazz bass, similar sounding to the Pultec emus I have.
Don't know what masses will think but it'll get used here.
