So I was about to spend ~500$ in pedals until I heard about this HD500X. Now I had an original and a pocket POD and loved em, I'm hoping this pedal board/ effects processor works great! How is it with a Spider IV 75W? Because I am also building a little practice 1x10 half stack with my BlackStar cab and either a Peavy Valveking micro 20W head or maybe a 15-Watt Orange head..what's everyone's experience here with the 500x?
