D'Addario Accessories PW-CT-9V DC Power Adapter – Minimize Need to Change Batteries on Pedalboard and Other Devices Requiring 9V – 500mA Max Current – Tip-Negative, Sleeve-Positive Power Supply

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.

worked great, no problems

Pretty good! It send the exact right amount of power to my pedals, FIVE STARS!

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。
