[QUOTE="Ampdog, post: 919931, member: 144"] Further to previous post: Said 'proper' operation of tone controls of log fashion is further only so if nothing else is hung onto the circuit internally or if e.g. the load it feeds into is not high enough. (There is no end to the variations found in practice - goodness knows for what purpose or for whose hearing - lame old topic again!). Most such circuits are best fed from a low input impedance, succeeded by a high load impedance. Just for general knowledge. And should it be necessary to point out again: At flat settings any properly configured tone control circuit has zero amplitude variation and zero phase shift in its pass band. [Sorry to seem to always play the policeman; not my purpose. But I wish someone would for a welcome change put up and indicate precisely how tone controls affect (usually meant negatively) sound quality instead of lamely perpetuating ancient folly. The electronics are dead simple.] [/QUOTE]
