Sitori Sonics Brownies & Cream

It's one of the best sounding Marshall voiced pedals I've heard.  It can go from moderate boost to searing over-the-top crunch.  It's not harsh, but it also is not tame, and has good dynamics. 

From Sitori Sonics previous website: "Everyone likes their brownies a bit different.  Ours features extremely interactive controls for a wealth of tones to suit your every overdriven and distorted whim.  It is by far the best way to add a second or third channel to your setup. At lower gain settings you'll get a good boost to push that crunchy tube amp over the edge, a true tone and sustain extravaganza.  Mid-gain settings give a very dynamic tweedy growl.  Crack the gain to the top and thou shalt shred.  No need to destroy that lovely tube amp with a variac Eddie! Be amazed at the dynamic touch sensitivity that is normally only found on the over-hyped $300-$500 units.... THIS is the inspirational tone creator that will keep you playing when you should be sleeping."
