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

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.

Excelente adaptador, funciona bien con mi pedal Zoom B1X four

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

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。
