There are a few FI factory presets that are comparable to the ones in the MXR. Eg patch 86 covers lots of classic territory and can be tweaked to taste in the panel. Granted, the presets are a bit more spread out across the pedal.
Sure, the editor has a lot to learn but working with just the pedal interface, you can achieve a lot.
That the presets aren’t to taste is a fairly easy-to-remedy problem. I’m hoping to refresh the factory presets a bit to account for similar comments though. In fact, I’ve already programmed and shared a fair amount of classic patches. Perhaps just making those part of the factory sound set would address some of these perceived shortcomings.
