Looking through my presets (PodFarm via UX1), I find that an awful lot of them are grayed out (as opposed to highlighted). I can still select those presets, but then I can't use certain components in the signal chain. I imagine those are presets included in higher priced devices such as the POD. I haven't tried it yet, but I suppose I can replace those useless components with models I CAN use. But what's the purpose of including them in my version? This isn't really a problem, more of a philosophical question.
