Seller's description

The MXR/Custom Audio Electronics MC401 Boost/Line Driver is a straightforward, professional-grade clean boost pedal designed to increase signal level without substantially colouring your core guitar tone. Developed in collaboration with Custom Audio Electronics, the MC401 provides up to +20dB of clean boost, making it equally useful as a solo boost, signal conditioner or line driver in larger pedalboard systems.

This Pre-Owned example is in Very Good condition.
