Used Boss PQ-50 Pro 4-Band Parametric Equalizer Rackmount EQ with Power Supply

The Boss PQ-50 Pro is a vintage four-band parametric equalizer designed for precise control over your instrument or audio signal. Part of the Boss Pro series, this Japanese-made processor offers detailed frequency shaping in a compact half-rack format.

Unlike a traditional graphic equalizer, the PQ-50 provides independent frequency, level, and bandwidth controls for each of its four bands. This allows musicians and recording engineers to target specific frequencies, reduce unwanted resonance, add clarity, or shape the overall character of a sound.

The PQ-50 is a useful addition to guitar and bass rigs, recording studios, synthesizer setups, and other audio applications where detailed equalization is needed.

Its straightforward analog controls make it easy to dial in everything from subtle tonal adjustments to more dramatic frequency boosts and cuts.
