I've used this stomp box for several years now. It's build is sturdy, and the battery lasts for a long time without replacing. The little carry case is very nice indeed. However, the dry sound has almost no bass, but I found that if you tape a small cloth to the top and EQ the hell out of it, you can get it to sound half decent. Just don't expect it to sound like a kick drum. There are also other problems with the design and quality. Although the material is meant to be non-slip, I've found that it slips on almost all surfaces except carpet. I use an old mouse matt underneath to give grip and this works fine. Also, this material has come away and I've had to glue it back several times.
