    has anyone tried the trick in the back of the current recording mag, basically a resistor between pins 2 and 3 (with a break out cable) of 600 ohms or so to better match up with some preamps?

    It would then gibe less with some *other* preamps, ostensibly.

    Think where something as bullet/idiot proof as the 57 is concerned, one might do well to let sleeping dogs lie.

    But the mod can be in the cable or connectors so you don't really mod the mic or preamp, just a spare cable or connector.

    The article also mentions that some preamps like a Groove Tubes one, adjust impedances optimally and wouldn't benefit from the cable mod.

    Most mics want to see a load in the range of 1k to 1500 which is what most pre's present. The 57 and similar mics want something closer to 500-600k or so. The the patch cable introduces resistors to lower the load the mic sees to that ballpark

    Thats not quite right. Some pres have a variable resistance that can be set by the user. The pre itself doesn't adust itself on the fly. The GT brick for example has load of around 600k or so by design so the mod is unneccesary with that pre
