Amazing amp if you love a pure, clean, deep and warm sound (not muddy). The amp is very quiet and works great with pedals too (FX loop), e.g. I use it with the Zoom Multi Stomp MS-70 CDR (bass as well as guitar), which creates an overwhelmingly clean soundscape and endless harmonics. Anyway, it works with any type of pedal, depending on your style, but even overdrive or distortion pedals will sound pure.
Unlike what I read in one review the Warwick BC80 delivers a nice slap sound, but again it's a warm sound compared to for instance the thin Hartke sound (but obviously that is a matter of taste).
As a solution for the bright power light I've covered it with a little Beanie Boos toucan bird ;-)
Finally, to get a good idea of its sound I'd recommend the YouTube review 'Wolfgang Schmid über den Warwick BC80 combo'.
