Mesa Boogie Grid Slammer

I was in two minds over posting this because it is almost exactly an Ibanez TS9, but I thought I would just because if someone does want to build one they have a ready made layout and so won't have to look up what changes to make.  To emphasise how close it is I've also included a toggle to switch between Grid Slammer and a TS9. Basically the difference is just a Timmy clipping diode arrangement, but if anyone wants a Grid Slammer or even a TS9 then at least this will give them two pedals in one. :o)

How much mileage are they going to get out of this design?

Info from Mesa about the original:

The GRID SLAMMER™ Overdrive is an overdrive pedal that produces a variable boost in gain over a wide range with a classic, guitar-centric midrange bump that enhances many different playing styles. It’s a true overdrive “specialist” that covers an amazing array of what many top players consider the most expressive and musical ranges of overdrive. From sweet, subtle breakup to a harmonically smoldering overdrive that can both sting and sing, the GRID SLAMMER sets a new bar in legendary overdrive!
