1- AnalogMan Sunlion 2- Zendrive 3- Turbo Rat clone 4- AnalogMan modded SD1 Before I got the Boss MS-3 I used to play my Fender DRRI cranked to 6 or so with a clean boost pedal at the end of the chain as a pseudo master volume knob. The amp set that way didn't like the MS3 at all. Now I have the volume down in the clean zone @ 3 or so depending on the gig. What a different world that is getting drive from pedals instead of the amp. One of my previously favorite pedals was the AM modded Maxxon SD9. It doesn't play well with the current live rig (P90 Reverend > Boss MS3 > Fender DRRI. I also loved the EH Double Muff and want another Muff pedal (Thorpy or JHS). It also isn't liking the change to the MS3 or playing the amp "clean". What I think is that the MS3 just isn't ideal for a cranked tube amp, or I just haven't really figured out how to use it that way yet.
