I did previously, but I wasn’t sure of what “COLOR” was suppose to produce. I just found some sound clips at http://www.home-wrecker.com/badstone.html that give me a good idea of what to listen for even though they are from similar model (no trim pots).
The upper 2 trim pots I think I have set or close to it, its the lower right one that seems to do nothing. That is what makes me think its tied to the color (PHASE/VIBRATO) switch.
