If I leave my delay pedal and tuner on all the time and switch them on and off with the footswitch, won't this wear out the pedals quicker? What's the advantage of switching the FX with the footswitch? Does it take the pedals completely out of the circuit, thus providing a purer tone? My tuner is true bypass so I could leave it in-line with the guitar and tune with a mute that way but if I use the tuner out of the amp, it's just one less thing in the signal path. Any thoughts on this stuff from folks that have had a chance to go out and gig with their Mark V and pedals?
