I don't know what to think about that myth, Joey. I know that the low impedance does not react well with certain stomp boxes, especially germanium fuzz circuits. That said, my S1 has no problem driving a pair of small combos and they'll break up much the same as they do w/ a passive guitar (the closest parallel for me would be a P-90 SG). The high frequency content in a series guitar isn't as shrill as say the ice-pickiness that can plague strats and teles, but if you don't know how to dial it out, i guess that can be a turn-off too.
