I am looking to tame my Fender Hot Rod Deluxe.

No, you are looking to *lame* your HRD...

Some suggest a 100W Audio Taper Pot connected to the effects loop.

Such a thing would be about the size of the NYC phone book...
they or you probably meant *ohms*, not *watts*. Does the
HRD not have a master volume? No wonder folks complain
about it being loud...

If I waqs to try a dummy load, couldn't I just connect a high power
8ohm load to my external speaker out? Wouldn't that cut the load to
the internal speaker?

Yes, it would... the lower the dummy load impedance, the
softer your amp would get. You should be aware that you
would be working the output components overtime doing
this... and into a mismatch, as well.

I have read that I would need a reactive load, but many DIY kits are
for a load connected between the amp and the speaker. What about one
connected to the external speaker out?

Merely connecting a box 'between amp and speaker' doesn't
tell us whether it's in series or parallel... could be either way.
Connecting a load to your external speaker output is connecting
it in parallel... lowering your impedance, which is probably the
safest way to go, in that lowering the impedance may work the
tubes and transformer harder, but won't result in flyback (high)
voltages on the output primary components.

Most anything you do in this regard will change the tone...
be prepared for that. If you are looking for the same
tone at lower volumes, good luck. If it was my amp,
I'd put it in the closet, or in a big isolation box, and
crank it and have fun. If you are looking to tame your
on-stage volume, I'd suggest some kind of gobo or
baffle... personally, I tape a piece of cardboard across
my combo when I play out, works wonders (it's a 100w
Marshall). Use a cardboard box... tear out one side, then
tape the remaining three sides across the speaker board
with an air space, like this (warning: lame ascii art):

and put the mic (if used) inside the trapezoid. I think you'll
find that cardboard boxes and tape are readily available at
your local venue.
