Works on my Boss GX1B multi pedal.Seems well built and has a decently long cord.Seems quality and fits all my Boss pedals, so I just got another one.Hope this helps someone !Have a great day !!!😁👍

No issues at all. Powered up my RC-500 just fine.

I purchased this PSA power adapter as a backup to my original BOSS PSA-120T. I placed my own label on this new one so I wouldn't confuse it among all my other power adapters.I use a Roland BOSS DS-1 Distortion Pedal. I removed the battery from the DS-1, plugged in the new PSA power adapter and it powers the pedal with no issues.I use my BOSS DS-1 with a Mic inline for harmonica playing. I turned up the volume controls on the DS-1 and cranked up the powered Behringer monitor speaker and I did not detect ANY dirty noise or hum while the mic was open and hot at about 50% gain and with it turned completely down to zero. I cranked the DS-1 and Mic back up and jammed out some blues riffs and the DS-1 pedal was generating distortion as expected (without a battery), so I know the new PSA adapter was powering the device just fine.So far, I'm completely satisfied with this new PSA adapter. I will continue to use it for as long as it will last and only revert to my original BOSS adapter if needed.Please note, this power adapter did not have a Ferrite Noise Filter attached to the cord. Depending on your use and where this power cord is located and laid out, it very well is subject to picking up interference from nearby electronics or other power cords. You can purchase a pack of noise suppressors from Amazon for around $7. (Search for "Ferrite Noise Suppressor" and look for a pack that contains a small filter).Rock On Fellow Musicians!

Roland and Boss are sometimes finicky on 9v adaptors they work well with.This adaptor worked perfectly with both the vintage Roland JV-1010 and the Boss Dr Rhythm DR-202.Does not introduce any buzz, which is common with lower quality power supplies.The size is smaller than most old wall warts, so very good ... as two fit back to back on my powerstrip with no space issues.I just wanted to write a review stating the good quality of this adaptor, because I bought two of them and both work perfectly on the devices listed above.The only con might be that the cord length isn't the longest. It's working for me, but if it was a foot or two longer, it would have increased utility in some situations.

Nothing special. It works well and has no issues. A little bit longer than what I use it for, but for a live show I'm sure it would be amazing. It can power most things that use a 9 volt or lower, but that's it.

Great price for replacement power supply for guitar effects pedals. Worked on my Boss Delay pedal and my Morley Wah pedal. Small converter box too, so doesn't take up a lot of power strip space (well, not as much as the bigger ones anyway).

Note that it's Negative Polarity. Where the C is open indicates the polarity. Negative Polarity means that the center is Negative and the outside is Positive. Make sure that the Voltage is right and it's ok to go somewhat over on the milliamps.

It's great

Works on the BOSS VE-2 Vocal Harmonist (which arrived without a power adapter, can you believe it). It is small - might be easy to lose if you're gigging. I'd suggest attaching a neon tag of some sort. Negative pin. Works fine.

Es compacto, ligero, con cable grueso, no se calienta para nada.Me encantó, funciona a la perfección y es muy fácil de guardar.

Funcionan al 100, cumple su función

réponds aux attentes, fonctionne bien.

This adapter did not power my Boss VE-2. Either it was faulty or it is not the correct adapter for this unit. I don't know... Returned to Amazon for credit.
