[sdiy] "Audio" vs. "Log" taper

[Brice D. Hornback]

Antique Electronic Supply...

...carries an inexpensive stepped attenuator.  Here's what they look like in
"kit" form:

These are inexpensive versions (but still pretty decent quality).  Here's
another link that has just the boards/switches (you supply your own
resistors):

These can be reasonable (from the above sources) or WAY out there.  Yes,
there are people who pay >$1,000 per meter for interconnect cables too.

Enjoy!
