yes, i need a user friendly digital delay for live and studio work. not sure how easy the Line6 DL4 or the boss DD20 are for live use. i need one that's easy and reliable at the same time. and i've also read about the Nova Delay being easy... i've never used digital delay before. i need it for spacey sounds, reverse, echo, tap tempo, all the usaul sounds. i need it to be easy to use live and be able to recall the settings... help me...please.
