I'm also thoroughly ashamed and embarrassed to have gigged the offerings from zoom, the digitech RPs, various pods, boss GTs and roland VG gear, korg, vox, and a host of others....usually I'd play a total of one gig with them believing they'd sound great, and ditch them in favor of my amps again. I think I played a couple gigs with modelers like the xt live and the VG-99, before ditching them, but the majority of gigs saw me pack away these 'modelers' after the first gig!!
I also used eventide and tc electronic gear for fx before Fractal, with an engl preamp and a rack mount tech 21 psa......that's also a modeler, but of the analog type! Actually was pretty cool, 1U and digital preset recall of the analog values set by the encoders or something like that.....
