Amazingly quiet and sweet features considering the price
I was using a one spot for about 7 pedals, which I honestly didn’t think was that noisy. When I finally pulled the trigger on this brick, I was floored by the difference…silence. No feedback, noise, nor hum was audible. Yes, that’s what it supposed to do, but it’s also lightweight and has 2 18v inputs, which ultimately was the selling point for me. Although it didn’t fit underneath my pedalboard (metro 24), I velcroed it in between pedals and its fine. Granted, I’ve only had it for a few weeks, but it’s MXR, so the quality is there. Decently priced compared to most power supplies, but even some of the pricer ones have less features! So worth it!

Didn’t fix my hum.
I am running several pedals into my half stack Vai Legacy tube amp and getting a hum mainly from my boost pedal and compressor/sustain pedals. I bought a Furmin power conditioner and then the iso brick but still have a hum. I guess I’ll just have to get a noise gate? (my old one died, maybe from too much noise! Lol). I researched several isolated power supplies and I believe this is a good value, but didn’t solve MY problem. It may solve yours, but it’s hard to recommend something that didn’t help me.

Nice brick.
This little unit seems of high quality. I was using an adapter with a daisy chain of 9 volt supply for my guitar pedals and i was getting a buzz in the audio. This mxr iso-brick solved that problem very well. I especially like the fact that a couple of the ports in the brick have adjustable voltage knobs. I think this is very useful for those who have a couple pedals that might require a different voltage. The little blue lights allow the player to see which wires have active connection, so that takes some of the guesswork out of troubleshooting. Very pleased with this and i felt 128 bucks was a very good deal for new product with all the little wires included. Kind of glad i ponied up the little bit extra for a superior product rather than get stuck with a lesser power supply.

Flawless B Stock MXR M238 ISO Brick
MXR M238 ISO Brick. Flawless B stock, no physical flaws visible. Better than the original I purchased a couple years ago. Original V trimmers were not straight and had these foam rings to keep from turning in transit or by accident. This new version trimmers are straight, must be upgraded pots. No foam ring surrounds. New version LEDs have switched positions from the original brick. LED main power indicators are reversed from the original bricks. I also noticed when powering down the original brick's main caps take significantly longer to discharge. Not an issue, just an observation. LEDs fade longer on the original. I checked voltages on all outs, all within spec. Solid cable connections. I tested resistance from like + and - connections from one out to another with power up, infinite ohms on all tested. Guess it is indeed isolated outs, really good deal for sure.Read full review

Just about good as new
Good value, works perfect. Really more connections than I need. Will fit under my new pedalboard fine. I think the only imperfection was one of the pins on the box itself was a little bent. No big deal, still works on that pin.
