I have a Greedtone OD clone and a Human Gear Animato clone with blend. The Greedtone has an extra switch that allows for the original sound + two different highs rolloffs, one similar to an SVT 810e, one that's a bit darker. That way, you can use it direct without a speaker sim. That pedal is about to make a return to my board as soon as I get this new LPF pedal I'm expecting on Thursday. The Animato would be useless for me on bass without the blend knob. It's still quite a scary pedal, but I love what it does to my other overdrive pedals, especially my MXR Bass Distortion.
John is just one of those guys who makes me sick with the talent has has. Plays great, builds and repairs guitars/basses great, builds and repairs electronics great. And if that isn't enough, he still has a full head of hair. Lucky bastard!
