Is this circuit any good?

Its an old tube mixer that i might be able to get my hands on. Would be fun to use for summing or recording through, or simply as a distortion box. It has 1 aux, and 6 inputs. Treble/bass and volume control for each channel and the aux. Cant really tell if they are line or mic inputs?

Is it a dead simple design that is not really worth getting your hands on (that is what it seems like to me).

Thanks
