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

## Questions & Answers

**Q: The spec says a Max Current of 300mA. I want to use it for BOSS MT-2 pedal which requires 200mA@9V DC. Can this be used?**
A: They've updated the product at least once now, it seems.  I have three I've bought from Amazon with 2013 copyright logos on the bottom, that have "Regulated" printed above the large "ADAPTOR" verbiage, have a 300mA rating, and are a larger cube shape and are much heavier.  

The revised version drops the 'regulated' verbiage on the box front, has a 2018 copyright, has a 500mA rating, is a rectangular shape like in the current Amazon photo as of 2020, and is MUCH lighter in weight. 

Both have the exact same model number PW-CT-9V, and UPC code 0 19954 95097 2.

**Q: I've purchased 3 of the 9volt Planet Wave Adapters for my Fender Mini Twin Reverb Amps. When I plug them in, I only get a humming noise. Troy,txs**
A: That not a question, but I'll turn it into one and try and answer that question that I just wrote. "Why do I get a humming noise when I plug my planet waves adaptor into a mini twin fender amp?"First off, does your mini twin work with a nine volt battery?  Check that. If not, then the amp's broken. If yes, continue. I just checked, and the mini twin seems to be center negative, like the adaptor. Still, check to see if your mini-twin power in is expecting a center negative power supply.Perhaps the power supply input jack on the mini twin is broken?Perhaps you've gotten three bad power supplies.  Have you checked them with a multimeter?Good Luck.

**Q: If I have a splitter, how many pedals max should be plugged into one power supply?**
A: Hey got to your question late, but I agree with AJ Rugged's answer.  The Planet waves 9V power adapter is designed for use with one device with a power draw of no more than 300mA.  I do not recommend using a splitter for this power adapter, or any single adapter for that matter.  Shop around for a power supply that will power the number of devices you will be using safely.  Perhaps here on Amazon?  Be safe and good luck.

**Q: Does this power supply work for my dymo label manager 160? it calls for 9v 2a.**
A: Absolutely not. 2 Amps is 2000 mA, this supply is rated for 500 mA so it can only supply 25% of the current your device needs.
