Is there a good simple remote control volume adjuster box?
Whoops.
I said a FET attenuator, not a FET. There are such packaged devices.
As they work in "bulk" mode, there should be no reason for them to
introduce significant distortion.
Isn't each individual step effectively an extra active device in the
signal
path?
No.
Think of a simple two-resistor L attenuator -- which is what I'm talking
about.
The FETs are not used as amplifiers, but as variable resistors.
