Tom, there ARE various caves and caverns to select from on the Boss pedal. And, what is also cool is that you stomp on it at the end of the tune and you can talk into the mic and not sound like God. Unless of course, you WANT to sound like God. The switchology on the box is easy to understand and you can go from your own private small cave to St. Paul's Cathedral with 10 seconds of reverb. It also has a delay function for when those metal bands ask you to don the spandex and play heavy whistle with them.

All the best,

Bob Pegritz
