The One Control Purple Plexifier is an overdrive/distortion pedal that recreates the sound of a 1960s Plexi amplifier in an Amp-In-A-Box (AIAB) format. This model emphasizes the thick distortion characteristic of vintage rock and the dynamic response of a tube amp, with a simple knob configuration for ease of use. A paper case (as shown in the photo) is included with the unit. The pedal's functionality is not an issue. The unit has few scratches and is in good condition, I think. Since the criteria for judgment differ for each person, please check the photos. It has been stored in a non-smoking and pet-free environment. This pedal can reproduce the distortion of a Marshall Plexi amp in a compact pedal, allowing you to achieve a tone close to that "brown sound" regardless of the type of amplifier. It has a high responsiveness to picking nuances and guitar volume control, and covers a wide gain range from clean to distortion. Controls (Knobs/Controls) 3-knob + trim pot configuration: • VOL (Volume) Adjusts the output volume. • DIST (Distortion / Gain) Sets the distortion intensity (gain amount). • TREBLE (Treble / Tone) Adjusts the tone, mainly in the high frequencies. • MID Trim Pot (small pot on the side of the enclosure, etc.) Fine-tunes the mid-range boost/cut. It's a trim pot, not a front knob like 4K. Sound Characteristics/Behavior • Recreates the tone of a typical vintage Plexi amp (Tight low end, clear treble, rich mids) • Highly responsive and dynamic Responds sensitively to the strength of the strings, allowing expression from clean to distortion with touch. • Wide gain range Supports clean boost to classic rock distortion to relatively high gain Thank you for viewing.
