GOKKO Mini Pedal Power Supply with 6 Outputs (GK-37)

Does the job, it’s small and fits under my pedal board with the included velcro. No noise whatsoever from this little guy. Great price too. Good quality.

I have just a small pedalboard at home and this power supply is perfect for it!! Fits just right underneath my board and more than powers what I need, with even room to grow. Highly recommend! No noise.

Works great! I use this on a small bass rehearsal board with a Strobostomp, MXR M87 compressor, Boss GEB-7 EQ, and an MXR Badass Overdrive. It’s perfect and cheap! My much larger gig board uses a $250 Voodoo Labs supply, which would be overkill and a waste of money for the small board, This little guy delivers nicely.

This is a totally adequate power supply. Very compact, but does feel sort of cheap, like it won't last very long, although I've had mine (and left on) for at least a year now with no issues. Includes wall wart power adapter, and power cables. I cant really tell if it's truly isolated outs. I was using a Onespot + daisy chain cable, and this is certainly a step up and solved some noise issues i was having. I use mine velcroed under a planet waves pedalboard.

This product does not disappoint. I powered my whole board off of one as I utilized these 3 way splitters. I’m aware that sort of defeats some of the purpose, but having 3 isolated to one line beats all 12 on the same daisy chain. You just need to be mindful of the ma #. All of my pedals are 9V luckily. Most run 15-30 ma. So I can put 3 all on the same 100 ma line and am golden. Plus I rarely have more than 2-3 running at once across the board. Now my Wah is 300 ma and it has a dedicated 300 line. Digital Reverb is 100 ma so it has its own. The balance are well sub 100. This little box clears out the last little bit of hum / hiss that my hum destroyer didn’t get. The pedal power and hum destroyer are both Velcro’d beneath the top deck. I couldn’t be happier.

TL:DR - It’s Quiet, It’s Small, It’s in a metal housing, it comes with cables and power supply, it works well. Full story: Bought it to power my 4 pedal acoustic board. It’s running a Boss AD-10 (300mA) a SA Collider (300mA) and a Smolder OD (100mA) and it’s doing it well and quietly. YMMV. Some people complained of noise and depending on your signal chain and pedal combo that can happen. Everything plays differently. Mine works great and has ZERO noise. It’s tiny, it stuffed right in the back corner of my board and disappeared. If I had to give a gripe it would be that the power supply cord for the wall is a touch short but it doesn’t matter to me cause I run it into a power strip that sits right behind my board anyway. Also the supply plug is rated at 1A so I’m not sure how it would act if you tried to max out the little guy. Also there’s no I/O switch so it hot when you plug it in and not when you don’t. Not a deal break as many high dollar units don’t have one either. Let’s be real, it’s $25 and it’s made of metal. That’s a lot to ask for anymore. So far so good, bought the 2 year warranty so I have 2 years or more of no worry power supply. Its a cheap gamble really.

Overall I’m disappointed. I had the perfect use for this as my pedalboard required exactly 6 lines of power exactly rated each for the current that this supply provides. But while power seems to be maintained just fine while all 6 of my pedals are connected, the audio output of my A1X multi-effects starts sending a really annoying high pitch noise to my amp whenever it gets connected to this supply. I tried all 6 ports connected individually to the pedal, but got the same high band noise every time. I’m pretty sure it’s not my effects pedal, as the noise goes away immediately if I connect a different, single-line supply to it (I tried two different brands: D’addario, and the original Zoom supply) or if I let the pedal run on batteries. I’ll guess I’ll try to open it and fix it later; I’m just guessing but probably someone cheaped out on the filter caps or something. So if your setup requires any sort of sensitive pedal I say you are better off getting something else. High noise issues like this are really impossible to manage even with filters if they get in the signal chain.

I own several of these; super quiet and perfect for any small board. Using a coupler you can power a Line 6 HX Effects or any power hungry effect.

I dont know to this brand why they put 500mAx2, 300mAx2, & 100mAx2.. 6 output but the total output only is 1000mA hahahaha... useless... total current of out put is 1800mA the free adaptor is 1A ... my goodnezz... so I used my 18v 2A adaptor to maximize all the output but unfortunately it create hummmsss... so i have hx stomp 930mA, nano cortex 600mA, buffer 110ma and mxr bass preamp 83ma and it creating a annoying humm.. so i remove the nano and let the hx stomp and the other 2 pedal in the psu and the hum is gone... please dont trick your customer with this stupid and nonsense gokko gk-37 item...

I prefer to power guitar pedals with a mains adapter instead of battery...I am prone to forgetting they are plugged in and the batteries can drain. Lol. This unit comes with long enough leads to make a suitable and uncluttered effects board. There is no buzzing ! Cheaper power adapters can make pedal buzz, this item is great. It works really well, feels good, it is a reasonable price . It is most usable .

I love how compact this is. For a small board with 4 to 6 pedals this is perfect. You could use on a bigger board with a daisy chain as it has a few ports with 300ma.

I power a homemade midi switch containing Arduino nano, a spark boost, a polytune 3, a TC X4 looper, then double up the 500mA outputs for my HX Stomp. I have had no issues, it's so small it's in the top corner of my pedal board. No bright. Lights, just sits there and does the job. Very happy.

Works great and is nice and small
