For lead tones, using a bridge single coil often sounds shrill. One solution is modifying your strat and connecting one of the tone controls to the bridge pickup, but even for those who have done that mod some times it's desirable to have a single patch that takes care of setting the guitar tone control for you.
Fear not, Low pass pedal in the KPA to the rescue
Try it with the following settings before the amp block:
Manual 7.3
Peak 0
Mix 83%
(leave the remaining settings at their default values)
If we had control over the slope of the low pass it would be even better, and a level control would also be nice as it'd enable this effect to be used as a boost by itself. But it's pretty nice as it is, the mix control is key for allowing some of the direct signal through and thus emulating the real life imperfections inherent to this kind of filter.
Have fun!
