I've mainly been using an HD500 for effects, but until recently I hadn't run it in stereo. The panning effect with a triangle waveform is just incredible sounding. It seems to have a subtle 'chewiness' to it, so it's more than just a straight-up panner effect. It's much more pleasing to my ears than other stereo effects like chorus or phase shift. Anyone else digging a stereo trem?
