For the life of me, I can't make heads or tails of the explanation in the SWR 750X manual (SWR's copywriter baffles me every time, like magic; it's amazing). Cut to the chase: How could the limiter LED come on at bedroom levels, and how could it come on without the preamp clip coming on? Is it limiting the input from the final stage of the preamp into the power stage irrespective of power stage output? I put the limiter knob at about 8 or 9 o'clock and every time I dig in on a Precision, the LED comes on...but the preamp gain is low enough not to trip the preamp clipping LED. Is this normal? It seems like it might be, but the docs have me confused. Bonus question: Is SWR's "OverDrive" effect supposed to sound pretty lame and fuzz-bassy? As always, thanks for any help.
