Superbly designed, with amp models and just about every effect boss ever made. There is even a'hidden' speaker cab available if you wish to record direct. Loads and loads of presets and so easy to make your own, with every parameter having a knob, no silly menus to trawl through just because you want to increase the delay time! Batteries not included, it will also work with a bog standard 9v pedal type power supply.
