The Maxon PQ-401 is the primary vintage parametric EQ pedal from Maxon's late 1970s and early 1980s lineup. It is rare on the used market and highly valued for its ability to surgically shape guitar tones in both live and studio settings. 

The Maxon PQ401 Parametric EQ is a rare, vintage Japanese-made pedal from the late 1970s/early 1980s designed for precise, surgical tone shaping on guitar or bass. It allows users to sweep through frequencies and adjust mid-bands, offering superior control over mid-scoop, high-end, and low-end compared to traditional graphic EQs. 

Key Features of the Maxon PQ401/PQ-9:

• Precision Control: Offers far more precise frequency adjustment than graphic EQs, allowing for targeted notch filtering and boosting.
• Three-Band EQ: Typically features controls for Low, Mid, and High, with a specific sweep knob for the mid-range.
• Versatility: Ideal for sculpting specific tones, from subtle tone-shaping to boosting, and eliminating "fizzy" high-end frequencies.
• Vintage Build: Made in Japan during the late 70s/early 80s, these are rare, sought-after, and durable units.
• Wide Mid-Sweep: Known for its ability to isolate and boost or cut specific, narrow frequency bands within the mids, making it great for solo boosts.
• Analog Sound: Provides a warm, vintage tone-shaping experience. 

This pedal is generally regarded as a studio-level tool for a pedalboard, offering a more analytical approach to tone than a typical graphic equalizer.
