The MXR CSP041 Custom Shop Hybrid Fuzz delivers the best of both fuzz worlds—combining vintage germanium warmth with modern silicon bite for an incredibly versatile, touch-sensitive fuzz experience. This rare Custom Shop edition is mint, unused, and comes complete in the original box.

Crafted with select NOS germanium and silicon transistors, the CSP041 offers a wide tonal range—from smooth, classic sustain to biting, aggressive fuzz. It responds dynamically to your guitar's volume knob and picking attack, making it equally at home in psychedelic, garage rock, and modern alt-rock rigs. Built in limited quantities, this Made in USA pedal features true bypass switching and high-end components throughout.

Whether you're a fuzz connoisseur or a collector of boutique MXR pedals, this mint, never-used Hybrid Fuzz is a must-have for your board or vault.
