Utility Parametric EQ

3-band parametric EQ with sweepable frequency (31Hz-16kHz), Q (0.1-30), ±12dB boost/cut—9-24V.

The Utility Parametric EQ delivers professional 3-band parametric equalization with comprehensive frequency control addressing players seeking surgical frequency sculpting impossible with standard bass/mid/treble tone stacks. Three independent band-pass filters each feature dedicated controls for center frequency (Freq), quality factor (Q), and gain (Level). Frequency ranges span 31Hz-1.6kHz (Band 1), 100Hz-4.8kHz (Band 2), and 300Hz-16kHz (Band 3), providing overlapping coverage across entire audio spectrum from sub-bass through upper treble enabling precise targeting of specific frequency ranges requiring enhancement or attenuation.

Quality factor ranges from approximately 0.1 (wide gentle curves affecting broad frequency ranges) to around 30 (extremely narrow surgical cuts or boosts targeting specific resonances), addressing scenarios requiring broad tonal shaping or precise notch filtering. Level controls provide cut or boost per band, Overall Level control provides global cut or boost at EQ output functioning as volume control with gain available. This three-way approach (per-band gain, overall level, and Q control) enables everything from subtle enhancement through aggressive frequency sculpting to feedback elimination via narrow notch filtering.

Requires Boss-style 9-24V DC center-negative power, extended voltage range (9-24V) provides increased headroom at higher voltages reducing distortion and expanding dynamic range. The Utility Parametric EQ targets professional players seeking surgical frequency control, suitable for studio recording (precise frequency correction), live sound reinforcement (feedback elimination via narrow notch filters), and players with problematic resonances in guitars or amplifiers where standard tone controls prove insufficient for addressing specific frequency issues requiring parametric precision unavailable in standard EQ pedals.
