[HAM] How do I get overdrive on an L-100 spinet?

[Peter Csere]

The signal going to your internal speaker is already amplified. Plugging it
into your Marshall head isn't exactly the best idea, as this may turn your
1974 Marshall head into a 1974 black box with the Marshall logo and lots of
dysfunctional electronics inside it.

That's probably exaggerating, but I've always been under the impression that
it's bad to put a speaker-level signal into a line-level input. You need to
bring this speaker output down to line-level and you'll be fine.

Of course, I'm not sure what the Marshall's particular preamp will tolerate.
