I just noticed that the FC7 has its jacks on the side. That's a deal-killer for me. Too bad -- and you'd think Yamaha would know better.
Not to pick nits ... but I believe it's the FC9 (Dual volume) pedal that has its jacks on the side. The FC7 is a "prewired" device (no jacks whatsoever - just a 5 ft cable wired into the pedal with a 1/4" TS connector on the far end). The cable on the FC7 is routed so that it emerges from the pedal on the front edge - not the sides.
