Depending on the rest of your gear and what kind of tones you're going after, you might possibly not like that fact that the SHO lacks a tone control. Not only are you unable to roll back the treble frequencies a bit (often desirable for smoothing out higher gain lead tones), but the SHO tends to add some extra high end sparkle, compared to when it's bypassed. That's because the circuit's super high impedance input (5 meg ohms, compared to the typical 1 meg or 500K of most pedals and amps) hardly loads down the pickups at all.
But the SHO might be just the thing if you like your leads and fills to have some edge to them so they cut through the mix, or if your rhythm tone is fairly dark.

Wouldn't the solution then be to put it AFTER dirt (or a buffered) pedal?
That way it would not be bringing over the pristing sound of the pickups...the pickups wouldn't be seeing that super-high impedance?
I actually have one, bought in a pedal-buying-bender so I haven't spent enough time with mine...I did like what it did directly after guitar, but not enough at the time...meant to try it further down the chain (maybe even after everything!) to see about exactly that.
