Phwoar, volume knobs.Arguably, the best kind of knob. And certainly the most enjoyable part of any decent audio gear - you can tell a lot about an amplifier or DAC by the texture and rotation quality of it’s primary enloudener.. But there’s no reason why a big, awesome, solid metal volume knob should remain the sole domain of expensive audio gear - I’ve got a design for an external ...
Audio pot with center tap for loudness control? - Page 1

The loudness control circuit is very simple. In the off position, C1 is not connected and C2 is shorted. This puts R2 in parallel with the lower half of the linear potentiometer R1. R2 is normally chosen around R1/10 so that R1 works effectively as a log pot. In the on position, C2 is in series with R2 and C1 is in parallel with the upper half of R1.
