Works great
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

Works great
Works great for my bass guitar pedal. I found an old Source Audio Soundblox multi effects pedal, but there was no power supply. This D’Addario one works great and fits right.

Fantastic and legit D’Addario 9v plug
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.

Its ok
Good for single pedal, on a daisy chain has a terrible high pitch sound and and after a lot of troubleshooting this power source on a daisy chain was the cause. That being said works great in single device

Quality product at a great price.
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.

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.

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。
