i've never been into pedals, always liked a very clean tone, but lately i've started wanting to create soundscapes and things different than i've done before. something i've always liked the sound of is an octave down with 2 different notes and a hint of fuzz. or sometimes no fuzz. but being able to adjust which 2 notes they are or having a low note and the actual note would be spiffy. so i've come to you. i don't want to spend too much while i get acquainted, and i don't want a massive learning curve. what i DO want is something that doesn't add hiss, buzz or noise to my sound and has octave down. octave up could be fun, too. fuzz only if the pedal can be used without fuzz. thoughts?
