D'Addario Accessories PW-CT-9V DC Power Adapter – Pedalboard Supply - For Pedal Board and Other Devices Requiring 9V – 800mA Max Current | Pedalboard power supply with 9V output and 2.1mm barrel plug

I needed another power supply for a wireless patch interface for my bass. Works great, plenty of power for charging and reasonably priced. Don't know if I could ask for anything more

Worked out well even though it wasn't item specific. Same voltage, amp configuration as it turns out.

Great power supply! 9v/800 mA is enough mA to power at least 2 to 4 pedals. I have 2 of these on my power strip/surge protector; they power my Overdrive pedal, 10 Band Equalizer pedal, Delay pedal...& in around 10 days, a Modulation pedal. I'm using 2, 1 into 2 pedals daisy chain "splitters". Knock on wood...I've had zero noise issues...& my pedals sound awesome. The cord length is very good too...more than enough length for the average musician.I do have 1 Con/complaint/suggestion for D'Addario; the way the plug prongs are positioned on the power supply, they end up covering outlets on my power strip...making the ones being covered...useless. But, their is a solution. I will be purchasing on payday; adapter "cubes" that are 90⁰ different...so I will have access to all of my 6 outlets. They are sold on Amazon as well, 3 for around $10. My suggestion to D'Addario, is having an option, to be able to turn/click the plug prongs 90⁰...so the power supplies will be efficient for everyone...& not covering/blocking the outlets next to them. This would be an excellent option! In closing, I am very happy with the power supplies. 800 mA is excellent, & I have zero issues with noise. The price is right...& D'Addario is a quality company, who have been around for a long time.

First to admit, I don't know beans about electrical specs, so I may oblivious to something critical. But I ordered this to power a Keeley Compressor Plus, and I noticed after a few days a persistent whine at about 2.4Khz. I hadn't noticed it at first b/c when recording, I chop off the quiet part the beginning and end, but it became apparent quickly enough. I swapped it for another adapter I had, and that one gave me a VERY loud hum. I tried a third one, purchased from Amazon, brand name WUKUR, and it works perfectly. Not dead silent, but 95% of the way there. I put this one on a tuner, where it works as it should. Did not realize that different adapters can introduce signal issues with pedals. Lesson learned. This one may work for you, may not.

Fantastic 9v plug for my pedals. No issues—maybe the other negative reviews mentioned counterfeits? This one sold and shipped by Amazon is legit real D’Addario because the box was perfect but even more telling is the D’Addario card with code for points/rewards program to use when purchasing from their direct website.

I bought this to use with a Universal Audio Lion 68 guitar pedal. Works great, no extraneous noise.

Product works well

I thought I was going to have to replace the power port on my Casio keyboard. I tried four different power cords. One of the power cords worked, so long as I moved it around a bit and held it in place. The other three did not work at all.I know that none of the cords were faulty, because I tested 2 of them myself and the other two were brand newOne would think that I would have stopped after trying four power cords, but not me. I took the keyboard apart and nothing appeared to be wrong with it. So I thought I would read some reviews and invest a couple more dollars. I am glad I did. This cord is thicker than the other ones I tried, the fit is snug, and the connection is great.Definitely, superior quality.

Excelente adaptador de corriente, no mete ningún ruido a los pedales y el cable es de un largo óptimo. Lo recomiendo amplíamente

Tried many 9V adapters, but this is the only one that worked.Unfortunately the infamous buzzing still exists.However manually grounding the Katana Mini (using its grounding screw on the backside) greatly reduced the buzzing.

Really good quality with zero feed back. Other power adapters I have tried can create a feed back hum/buzz this fixes that problem! I bought it to use with a guitar pedal and it's fantastic! No more need for batteries. It also powers mini guitar amps like the boss katana mini or similar battery powered amps. No noise or feed back powering the amps either. The cheap power adapters buzz and hum and make it annoying to use and this solved that issue. Well worth the few extra dollars!

エフェクターに別途必要だったので購入。特に問題ないです。もっと安くてもいいのになぁと、この手の品物の時にいつも思うのですが、仕方ありません。

There is no 0 star option else i would have choosen it. I bought this for my zoom g1xon but it does not work.. Wont even power up so i returned it. Worst purchase ever as it has been a month since i returned the product and the process required me to ship it and still no response about the refund
