“You could actually install a higher value pot in the variable amplitude adjustment and have the buffer provide lower voltage than the input while still having the low impedance drive, I've never had the need to do that, but it's an interesting idea.”
Recognizing it’s more clunky, would a voltage divider downstream of the buffer signal output, with variable pot in the divider, provide the same result? Alternatively how to change the pot in the buffer, and a part number for a suggested pot, would be fine too if it’s easy to disassemble w/o damaging the unit. Thanks.
