Vertex Tone Secret Overdrive Pedal

This is Vertex take on the Tubescreamer, but with some added voodoo; working on the TS into a Blackface amp combo. The 'grit' control manipulates the point of natural amp breakup, plus the 'pre-vol' control determines how hard the signal hits the 'amp' section. Plus you get a two band EQ, so you can determine the brightness and how much 'hump' is in the mids.
