“There are 256 different wave tables to use — you can get a wide range of sounds out of this effect. It does take a little while to get
the hang of using it with regard to your picking style. Playing dynamics have a lot to do with
the sound (and can REALLY open up the functionality). But to be sure,
it’s not for everyone. If it’s for you only good things
will come from having it.”
