Patent ID: 8324495

Claim:
A volume-adjustment circuit for equilibrating pickup topologies, comprising: an output signal line; a plurality of pickup leads; an m-setting pickup selection switch having a plurality of inputs, at least two outputs; and the m-setting pickup selection switch selects a different pickup topology for at least two settings of the m-setting pickup selection switch; at least two volume adjustment circuits each having an input and an output; at least two separate and independent signal paths each path having an input and an output; the plurality of pickup leads connect to the plurality of inputs of the m-setting pickup selection switch; the input of each separate and independent signal path connects to the output signal of the m-setting pickup selection switch, and the outputs of the separate and independent signal path connect to the input of the volume adjust circuit; and the outputs of the volume-adjustment circuits connect to the output signal line of the volume-adjustment circuit for equilibrating pick-up settings, providing separate volume adjustment for each pickup topology of the m-setting pickup selection switch.
