Another smaller but important update on the SVDS. I was able to exchange emails again with Mr. Schaffer during my Italian sleep-less night (majorly jet legged here, and so Mr. Schaffer having come back from Russia where he met his long time friend Sting of which he sent me a few pictures) and he confirmed me the following:
From what I remember (I promised: very dodgy) there was no switch per se.. . the XLR is the clean way out… the front panel “monitor” was never meant to be in line… but a lot (most?) guys used the monitor output, I guess sometimes to overdrive the front end of the amp (which the XLR output would not do).
You know - you can design something with one thing in mind, but once it gets out to the user, it can turn into a whole new ballgame. Just like writing a song - once it’s out there, the writer has like nothing to say about it !
