No they weren't, I have friends who work in the music industry and there was talk about the boss katana a long time before they were released, and they were not inspired by Blackstar, as far as I know the boss range is built on their cosm technology which Roland developed years ago and have continued to build apon and uses the same DSP chip as the boss gt-100, if any company really drove the market for digital modelling amps it would be the fender Mustang range.
