The sitori drive is a lower gain dynamic overdrive with a very transparent top end.  With single coil pickups, it has a beautifully open and airy tone, yielding more drive as you dig in harder with the pick.  

With humbuckers it gets the smooth creamy overdrive that you have always wanted.

In fact, damon johnson (whisky falls, alice cooper) is currently using it in this manner on tour with alice.

It can also be used as a nice clean (or dirty) boost to shove the front end of your tube amp into saturation.  we have had reports of the sitori drive being used on bass as well as the occasional electric bouzouki!
