I noticed the graphtech system is pretty involved. You have to get the saddles/bridge, then buy the hex system to wire it all in, etc... The roland system is pretty easy to attach and go.
I already have a ground control pro on the floor and could probably use it to control the bank, but it is pretty involved to get some of Jerry's signature flute, sax, trumpet sounds... I wonder if they have a pedal that can achieve these sounds without all this fuss? I had a fun time playing with it all, but not a $700 good time.
