I am still gassing for an Empress delay and at some point I want to upgrade from my SansAmp to the programmable version, both of which got me thinking. How does a pedal maker set up a preset option in a pedal like this? I've seen a number of pedals that I've steered clear of because a large number of knobs mean it would be too hard to switch settings at a gig. If it's something that can be done relatively easy by an experienced builder, why don't we see it more often. And would it be possible to mod a pedal to save presets? Just wondering.
