Bourns Expands Standard Resistance Values for Blend-Balance Guitar Potentiometers

Bourns today announced the expanded standard resistance values for its PDB182-GTRB Series L17 mm blend-balance guitar potentiometers. The series now spans 10 kΩ to 1 MΩ, adding resistance options for tone shaping, signal blending, and balance control on the same mechanical layout.

The PDB182-GTRB Series is used in electric guitars, amplifiers, mixers, synthesizers, and other audio equipment. Its dual-gang, center-detent design delivers repeatable blend and balance adjustment in a 17 mm package. The new resistance codes give instrument builders and audio OEMs a wider set of tonal configurations within the same series.

Because the expanded values share the same mechanical envelope and mounting dimensions as existing PDB182-GTRB configurations, designers can evaluate new resistance options in current PCB layouts and enclosures with no additional qualification of fit or form. Standard M and N taper options are available across the full resistance range.
