MXR Iso-Brick Power Supply M238
Jim Dunlop
Product Description
The MXR iso-brick power supply is small and light with tons of quiet, noise-free DC power on tap ready to run a wide range of pedal types without crowding or weighing down your pedal board. Each of the iso-brick power supply 10 outputs is fully isolated, eliminating gig-ending ground loop noise. Whether analog or digital, positive or negative ground, This power box has you covered. The MXR team broke down These 10 outputs to accommodate a variety of voltage and current requirements: two 9V outputs at 100mA, two 9V outputs at 300mA, two 9V outputs at 450mA, two 18V outputs at 250mA, and two variable outputs adjustable from 6V to 15V at 250mA. The two variable outputs can be used to emulate voltage “sag,” A drained battery effect sought by many vintage tone chasers. On top of all that, the iso-brick power supply comes in a small, lightweight housing that’s built like a tank. Features power on/off and connection status LEDs. Put this little box on your pedal board to make sure it runs reliably and quietly gig after gig. Pedal board-friendly size 10 fully-isolated outputs quiet, noise-free operation powers a wide range of pedal types—digital and analog, positive and negative ground (2) 9V outputs @ 100mA, (2) 9V @ 300mA, (2) 9V @ 450mA, (2) 18V @ 250mA, and (2) variable outputs adjustable from 6V to 15V @ 250mA variable outputs can be used to emulate drained battery effect on/off and connection status LEDs.

I can’t really compared this to other power units. In the past, I’ve always used daisy chains or individual plugs, but in an effort to clean up my gain stage (and my space), I decided I need something that could power a number of pedals with isolated power and 18 volt output options. I chose this one because it had a large number of outputs (10) with a good variety of power options (the two variable outputs were a real selling point). Plus, the price was good compared to other similar power units.
As for performance, I’ve used it for almost three weeks and absolutely love it. I have it powering five pedals: Polytune (9 volt 100mA), RC Booster (6-15 volt), OCD (6-15 volt), EHX Pulsar Stereo (9 volt 450mA), RE-20 Space Echo (9 volt 450mA). These all operate noise free and the unit runs cold. Overall, I’m very satisfied and would recommend it to anyone that is not too hung up on mounting it under a Pedaltrain Jr.
The unit itself is very sturdy and will hold up well to travel and gigs. Simple instructions included and I hooked all my pedals in and compared the before and after. Though it did some reduction of the ambient hum, it didn't eliminate it entirely. (I discovered that my guitar is the cause for the remaining him, something I still remedy with copper shielding tape.) I was a bit bummed, but I proceeded to discover an unexpected perk with this power supply.
When I started playing, I noticed a much sharper clean tone as well as an increase in master volumes without touching my knobs. As I messed around using my various pedals, (wah, distortion, sustain, flange, compression/sustain) I was blown away with how they all sounded.
Every effect sounds infinitely better with the M238. Signal volume is increased naturally and the attack and presence of each effect is crystal clear. I cannot wait to clean up my guitar wiring to get that studio-quality and interference free sound in the comforts of my house! Did yourself a favor and spend the money on a quality power supply like this one...
It is very small and pumps a ton of mA compared to similar pedalboard power supplies. It was the one supply that could run my whole board. I picked up a couple of these 2.1mm x 5.5mm DC Barrel Plug Splitter, 1 Male Plug to 2 Female Jack to split the mA from the 450mA jacks to power 2x ~200mA pedals.
Also another huge point that I didn't really see anyone talking about on the internet: it seems to power the Digitech Whammy 5 flawlessly. NOTE: this is the version 5 that is 9VDC from the factory (not the AC older versions). So the original Whammy power brick and input say 1300mA, but the Whammy manual says that it consumes <265mA. I think the adapter is a generic Harmon adapter for many things and so they just want you to use what they already make which happens to be 1300mA max. The pedal will only pull the required amperage from the brick at 9V, which again is <265mA and I'm pretty confident that value is accurate, otherwise it wouldn't be in the manual. To be safe I put it on the 450mA output and it works great!
Pedals I'm powering:
Korg Pitch Black Tuner
Digitech Whammy V (DC)
Visual Sound Double Trouble
Visual Sound Comp 66
MXR Smart Gate
Vox Time Machine
Switch Doctor generic amp footswitch with 9VDC powered LEDs

Definitely a happy camper now, super easy to install, doesn’t take up a bunch of space & the special part about no noise at all, no pops, squeals or hums, looks really cool with the blue lights to, going to put a blinder on the white light on top, almost got sunburned.
If you’re undecided on if it’s worth it, think Simon & Garfunkel, sounds of silence, totally beautiful !!!
