the only digitech rack unit i’ve ever owned was the OG ips 33 aka poor man’s eventide.
pretty limited mono in/stereo out and like the roland sde-1000 super easy to clip the input,
but it did have a nice analog warm to the sound versus other thin chipmunk pitch shifters of those days. if i could’ve afforded the rack space and extra dedicated loop switching/routing to kick it in and out of the signal path, it would have stayed.
the next version ips 33B added the delay component and was a better pick.
