No difference apparently - this one is designed for anything with a 1/4" plug, and I'mm mostly use it with my WIngbass anyway. I just want to try it as it would be ideal to have something so small, and I really like having reverb on tap too. Hopefully the signal to noise ratio is better... and I guess the more people that try it the more likely it'll be that the product gets better and better. I'd love a really well made super hifi version by someone like PJB or Roland!
