My experience with pedals is pretty extensive it used to be an obsession like it is for so many of us
I was looking around on You Tube and stumbled on a demo of the Miku Stomp and I thought it was the weirdest, coolest thing I've ever heard and I also didn't know that the Miku Stomp is modeled after a character called "Hatsune Miku" very popular in Japan. The pedal tracks surprisingly well with bass and would be killer on a six string. I use it primarily with guitar but if you can find one used it's definitely worth a try.
