Monoprice Power Block Fully Isolated 8‑output Guitar Pedal Power Supply for Up to 8 Guitar and Bass Effects Pedals 6V/ 9V/12V- Indio Series

I made a custom pedal board and decided to try this because of it's price point and features. I was super happy when i hooked everything up (5 total Pedals) and everything was operating perfectly and silent. I used on stage today around many Leds and a large Led wall. The power supply was silent even when 2 distortion pedals was engaged. I didn't take the cover up but I believe this power supply has true isolated grounds due to it's silent operation in a very noisy environment.

Nice quiet LINEAR pedal power supply for standard pedals with 2 ports at 9-12V, 2 ports with adjustable 6-12V, 2 ports at combined limit of 300mA. Note this PS will NOT support high current pedals. Good build quality. Tremendous Value!

Got unit hooked up and creates way to much hum and shuts off I took off pedal board and bought another I spot. Monoprice has to much hassle return policy I will eat the cost of product and move on. L. B.

Got it for $40. Would not pay 99--no way. Seems to work OK; have tried out about 3 basic pedals with it. Just using one right now. Power cord seems to get loose in its socket easily (the one in the unit, not in the wall). Caution advised. Have not had it very long, so don't know about durability.

Solid power supply. I tested it with notoriously noisy pedals and it was quieter than a standard wall wart with daisy chain. Oddly, the cables provided sometimes did not work in certain pedals. They fit but did not provide power. At first I thought this was just an isolated issue, unfortunately it was not. I purchased two of these power supplies. Various cables out of both supplies did not work in very standard pedals. When I changed cables to something not monoprice it was fine. Not a big deal for me, but someone else may only have this supply. It is also nice the supply has an on/off switch. Considering Price, features and problems I would probably give it a 3.5 star review but that's not possible. Overall a good power supply for the $$.

Unpacking this unit, I was very pleasantly surprised by its super sturdy build quality. The fact that it uses a solid three prong power cable instead of a flimsy wall wart was immediately a plus. However, I have to say that the choices that were made here in terms of outputs are weird to me. What most people need are rock solid 9V outputs, as many as possible, and maybe one 18V one. Instead, valuable real estate is wasted here on two 6-12V outputs. I understand that some people like the option of choking (under-feeding) fuzz and distortion pedals to mimic a dying battery. But that's such a niche use! Worse: The device I mostly got this for is not running with this brick. It's a UA "Dream" pedal. I admit that I didn't do my research in time, otherwise, I would have known that it requires a minimum of 400mA. But it runs on a humble One Spot, so I was sure this solid power supply wouldn't cause any problems. Well, it does. Also, it's not very practical that all the connection cables are the same length, ca. 15". A range from maybe 10"-20" would have been more pedal board friendly.

Performs as good if not better than any other brand of power supply I?ve used and much better price
