The Ultimate Secret Weapon Pedal! Up for sale is a legendary, vintage 1981 Ibanez PQ401 Parametric Equalizer, meticulously crafted in Japan during the golden era of Maxon/Ibanez manufacturing. Unlike standard graphic EQs, this parametric powerhouse lets you sweep and pinpoint the exact frequencies you want to boost or cut. It is highly coveted by tone purists for its incredibly musical, studio-grade control. (If you're in a pinch, it's also heavy enough to use as a weapon of self-defense.)

Provenance & History: This pedal comes directly from a private collection and was owned by a dedicated, working Central Texas musician who lovingly collected and cared for gear for over 50 years. It has been safely stored and is now ready to find its way onto a new board to create more music. My dad always had an eye for the tools that truly mattered to a live mix, and this PQ401 is proof.
