ME-80 : Great value and fully-functioned

I have used this unit solidly for three years, for rehearsals and gigging, and it is the only one you'll need. The effects are first-rate, as you'd expect from Boss, and the value is remarkable comparing to the separate cost of each effect.

PRO's: The unit is small, light, and the battery backup feature is very useful. The knobs are easy to see and use, and so much quicker to adjust than stepping through menus (which you can still do if you must). Very robust construction. Great effects with very low noise. Everything you'll ever need. Loads of patches to be found on the web. You can save your own to your computer. But the preset ones cover 90% of what you'll need.

CON's: The only things I don't like is that you must use a separate plugpack, and that the upper row of switches can be tricky to use without standing on something else. It is just a little cramped, but you can always use a separate MIDI controller if this is a problem.
