Of course, the main advantage this should give is price. I mean, guitar pedals are ridiculously expensive for what they are, mostly. Except for the rugged pots and switches, it's only a $3 to $10 aluminium box with either 40 year old silicon in it or some DSP. Although those programable digital pedals imply you have to pay developers (and probably specialised ones) and in my opinion they give you more pedal for your money.
