And that's the biggest problem I have with the Disting. When it's doing some high-end function, you feel like it's justifying its expense. But if you use it to emulate a couple of transformers and four diodes...I dunno, it just feels like a misuse of the module. MY ring modulators, for example, are all Tenderfoots...typical dual balanced passive ringmods, since you don't need power or really anything else to make 'em do their thing.
I should also note that NONE of those Tenderfoots are in a cab, btw. Both modules live inside patchbays, wrapped in electrical tape (sounds vaguely kinky, actually!) to protect the circuits, and with no external power. Gives me a stereo pair in my FX patchbay and also in the lab-gear one, and they work like a charm.
