Nothing works as well for 'that' sound.
This is a one trick pony. You will not use it on every song or even on most songs. However, it's a really great trick, and when you do have a need for it, there's nothing like it. This unit is built to take abuse and has an amp and speaker driver built in. The internal overdrive/distortion sounds nice but there's an effects loop if you have your own favorite that you prefer. All in all, a very usable, not to mention fun, box that will give you 'that sound' when you need to live on a prayer or feel like we do. :)
