Refine your audio with surgical precision using the Golden Age Project EQ-81 MKIII Vintage-Style 4-Band Equalizer. Designed for professional musicians, producers, and engineers, it delivers classic warmth and versatile tone shaping across a broad frequency spectrum.

The external 24 VAC power supply further ensures low circuit interference for cleaner sound.

• Four adjustable bands with inductor-based mid frequencies: Customize your sound using precise stepped frequency selections, from 33 Hz bass to 15 kHz treble, with up to ±18 dB of boost or cut per band for detailed tonal sculpting.
• Switchable shelving and bell modes: Bass and treble bands feature shelving or bell curve options, giving you control over the EQ curve shape and enhancing your flexibility in shaping the sound.
• Hi-Q switches on low-mid and high-mid bands: Engage high-Q mode to focus on narrow frequency bands, enabling surgical adjustments that are essential for mixing or corrective equalization.
• Individual band bypass: Each band can be turned off via the frequency selector, allowing quick A/B comparisons and streamlined workflow during sound design.
• Balanced and unbalanced I/O options: Connect seamlessly with professional gear using a balanced XLR-1/4″ TRS combo input and balanced XLR and 1/4″ TRS outputs, or integrate with unbalanced equipment via the 1/4″ TRS insert send/return jack without compromising signal integrity.
