【Product Description】 This is the "MATADOR PRE-AMP" preamp pedal made by Rockbox Electronics. The unique antique-style textured casing is eye-catching, and the sound is also distinctive, with a unique tone and drive. It has a 4-knob configuration with LEVEL, DRIVE, TREBLE, and BASS, allowing for intuitive sound creation. It features true bypass, minimizing signal degradation. The appearance has a slightly vintage design, but it has been used very little and is in overall beautiful condition. Operation has been confirmed. There are four rubber feet on the back for stable placement. It supports a center-negative 9V adapter for power, and the INPUT/OUTPUT terminals are also in good working order. It comes with the original box and instruction manual (in Japanese), making it recommended for collectors. 【Condition of the Product】 No noticeable scratches or stains (beautiful condition) Operation confirmed 【Included Items】 ・Main unit ・Original box ・Instruction manual/Warranty documents 【Notes】 ・Everything in the photos is included.
