The MXR M237 DC Brick: Rugged, Reliable Power Distribution

All-in-One Power Solution for Your Pedalboard

The MXR M237 DC Brick is a compact and reliable power supply engineered to support demanding pedalboards without compromising tone or space. Capable of powering up to ten pedals simultaneously, eight at 9 volts and two at 18 volts, it’s the perfect backbone for any gig-ready rig. Whether you’re running analog classics or modern digital power-hungry units, the M237 delivers consistent and isolated output with maximum reliability.

Designed for Stability and Signal Integrity

With a robust build and straightforward operation, the M237 ensures your effects chain remains noise-free and dependable. Each 9V output supplies up to 150 mA, while the 18V outputs provide up to 400 mA, more than enough headroom for today’s most complex pedalboards. Short circuit protection is built in via red LED indicators, keeping your rig protected and troubleshooting effortless. This isn’t just smart power, it’s bulletproof confidence on your board.

Built with Practical Features for Touring and Studio Work

From its multi-voltage AC adapter (100–240V) with international plug options to its plug-and-play design, the M237 is a top-tier travel companion. Whether you’re in a club, studio, or halfway around the globe, this power supply adapts seamlessly to your needs. Blue LED power status makes stage checks easy, and its quiet operation is ideal for both live and recording environments.

Complete Package Ready for Setup

This unit includes everything needed to get up and running: eight barrel-to-barrel DC cables, international power adapters, the original power supply, manuals, and the original box. With clean ports and fully functional indicators, this pre-owned unit is ready to plug in and perform with confidence.

Durable and Compatible with Most Effects

Designed with the industry-standard 5.5mm x 2.1mm barrel connectors (positive barrel, negative center), the M237 is compatible with nearly all modern pedals. Just be aware it’s not suited for positive ground pedals. Outside of that, this unit is a no-compromise choice for powering up your board with clean, reliable juice.
