JIM DUNLOP Dunlop M238 MXR ISO Brick Power Supply (11238000001)

I've looked at a lot of the popular power supplies on the market like some of the voodoo labs and Truetone 1spot bricks and this one seemed to have the right amount of outputs for the price. I'm surprised that these don't seem to be more popular. I had some noise before I bought this and now everything is quite and absolutely no noise (still a little pickup hum, but my noise gate squashes that completely; no power noise at all). The LEDs are very bright but I guess that is better than not bright enough. I have a Pedaltrain Pro and the cables were long enough that I was able to string my Time Machine nearly all the way to the opposite corner of the board. I was a little concerned about the "sag" outputs but it seems that you can just set them to 9V and they act as a normal 9V output.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 TunerDigitech Whammy V (DC)Visual Sound Double TroubleVisual Sound Comp 66MXR Smart GateVox Time MachineSwitch Doctor generic amp footswitch with 9VDC powered LEDs

I have had a Boss PSM-5 daisy chain to power my pedals for decades. I've recently been making changes to my stomp boxes and gear, and wanted to finally splurge for an isolated power supply to help reduce ambient hum. I have 6 9v pedals needing power of various amperage requirements, and this power supply was recommended to me by experts on a YouTube channel I subscribe to.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...

working as expected, no noise from the pedals

this will keep things powered and QUIET

I purchased this to use on a Pedaltrain Jr. I know a lot of you want to know if it fits under the board, and it does. However, because of the “T” shape of the rails, only the bottom plugs are easily accessible. As for the top row, there is not enough room to use the straight ends of the plugs. The right angle ends fit; however, to plug them in or unplug them, the unit has to be removed. This might be a deal killer for some, but it shouldn’t be. I actually purchased this unit to put on top of the board because 1) it looks cool, 2) it doesn’t take up much more room than a standard pedal, and 3) I wanted easy access to the variable output controls.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.

Works great, cut out any noise I had before and I'm able to power my Line 6 DL4 with it (with a OneSpot CL6 to convert from DC to AC of course). Takes up very little real estate on my board, and bright LEDs make it easy to see that my pedals are indeed getting power. My only complaint would be that the AC adapter is a little short, and that one of the knobs to adjust voltage came a little bent as there is a bit of space between the knob and the case.

My pedal board has eleven pedals on it, all nine volt, but note that this brick also has two eighteen volt plugs. It is very small and works perfectly. At the cost I paid, it simply cannot be beat.

The iso brick is small and light weight.The versatility as great.Dowfall : It seems that I have ground related noise issue. the power supply has only 2 pins (phase, 0 ref) and it doesn't have a ground pin so incase the 0 ref isn't actually 0 (this is the case in israel ) my pedals cause more noise then with my old plan power supply.
