Was watching the latest Metallica gear rundown, and they've gone to Fractal Audio Axe-FX units for this tour rather than lugging around their usual stacks. They didn't show Robert's rig but they showed what James and Kirk are using, and their techs said they use two each, have the sound they're using in one with the preset they need next loaded up in the one they're not using, then switch between units manually so there are no gaps when switching. Watching this video, all I could think about is that. Well, that and how cool it must be to have a tech work your effects so you can just concentrate on playing! But you mean to tell me that these high end digital products like the Axe-FX, Kemper, Helix, and whatever still have gaps when switching presets? I have never been able to try out any of this next-gen digital stuff, so I haven't gotten to see for myself, but when I can get near-gapless switching with this old Zoom B2 I bought years ago, why are Metallica's guitarists having to switch between two of them to get gapless switching? If it's true you can't get gapless switching, that to me is a giant deal breaker. I barely accepted it in the Zoom because it was $100 new, and at the time that was the quickest switching digital FX unit I ever used. And even that got irritating to me and I quit using it as soon as I could get enough pedals to replace it. I'm not interested in having to time my switching and alter my playing so nobody notices the gaps. That's just crazy talk to me when forking over $2000 or more. So those of you who have these high end digital setups, is that true that there's still gaps?
