Hey guys, I played an SD-9 along time ago. It was pretty much when I was first coming out of my metal faze back in the 90's. I can't really remember what it sounds like now. I was curious how it compares to things like the BB Preamp, Eternity and so on? I'm a huge Landau fan and I was wondering how much of his sound is an SD9. What is your overall opinion of the pedal?
