I just learned how to use the danmed thing. Here's what I've found. In most applications with higher-end equipment where you have pre and post volumes with the preamp (or at least pre-gain into the preamp and master for the amplifier,etc.) I've always been of the school to load the preamp just short of clipping and then using the master volume to adjust the output volume. With the WW amp I just figured out that if you do it this way you get a mushy and overly-present (compressed?) sound. I tried setting the master volume up, to 6-7ish in my case, and then using the preamp volume to adjust output volume. Below 1 the sound is a little non-present, but in the 2-4 range I get and incredible airy and much more accurate sound out of the thing. This worked exactly the same on both the green-light and amber-light models that I had in my house the other day, through a couple of different cabinets and with different instruments (slabs and bass). Now my fiddle with the FullCircle, through the Woods and into the Ampeg sounds RFG and I've also gained a lot of headroom volume-wise before infinite-sustain and feedback start creeping in. I also have enough control over the tone that I can set the cabinet on the floor without uncontrollable bottom end.
