I am doing nothing more than powering the unit up and playing through the presets. However, it could be the settings since i bought it used. 

Running it in front of amp

Not sure what killdry is but I assume it's the bypass setting. 

It isn't so much the time it takes to load the preset as it is the fact that it is cutting my guitar signal for a split second while doing this. I should have been more specific. 

I can't be playing through a fuzz pedal and click on a phaser, delay or any effect without losing my signal for a split second. Like a kill switch stutter. Not usable for a live situation like this.

Please tell me this is just some setting I am in or something and not a function of it being a digital machine.
