I love everything about this little box of wonders. I have used (and stil use) a lot of dirt boxes and the Les Lius is one of my favorites. If you're looking for a transparent overdrive then the Les Lius is not for you. This pedal was designed to emulate the sound of a cranked tweed amp and it does it with style. I mainly use it in the middle position (high power twin) on my Palmer Fab 5 amp. Awesome combination !
