Does it have a bypass switch?
Like I said I don't have a particular problem with the current setup and don't want to get into a "you're setup must be crap if you think you need tone controls" type situation. But I would question the "Tone controls are unnecessary as a good system doesn't need them" mantra which seems to have been passed down in hifi circles since ... well I don't know when, but my old man used to intone it 25 years ago.
95% of the time it may be true, but it doesn't account for stoned, half asleep, hungover or just plain incompetent recording engineers at the other end of the chain. If it can't be done without arsing things up, then fair enough I guess. Must say though, I don't want them on my Densen cos it wouldn't look half as cool with loads of extra knobs
