Why use 2 loopers?

["Brian Carabee" <compguy@bestweb.net>]

Hi List,

I've been enjoying my Boomerang for a few weeks now, and I'm starting to
develop some questions which I hope you don't mind my asking...

Exactly why and how does one go about using two seperate looping devices?
Maybe someone can explain to me the way they are used together (FWIW, I'm a
guitarist).

Also, is there a list of great looping recordings out there? I'd like to
hear what other people are doing.

Thanks!

Brian
