I'd agree with Shep here, Tom's (COG) blend is the only blend I've ever liked. Too often it simply sounds like you're diluting the sound of the pedal, need to boost the effect saturation as you introduce clean signal just to have it heard. My Knightfall 66 prototype is great though, I tend to only ruin the clean blend at about 30%, but as mentioned above, it's very musical.
