WUKUR 9V Power Supply for Guitar Pedals,Compatible with Boss PSA Adapter 9V DC for Pedals Like ME-80 ME-70 ME-25 GT-100 GT-1 GT-10 BR-80 RC-1 RC-3,5.9FT/1.8M Guitar Pedal Power Cable for Effects

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).

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!

So far so good...bought for Helicon FX pedal

Works with Boss DS-1, keep in mind you have to have a cord in the input side of the pedal to act as a switch, or it wont turn on. its a feature to prevent the battery on the inside draining when its not in-use.

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.

So far it works. I wasn't sure it would because Boss doesn't want you to buy any other ac adapter but theirs (theirs being $40!) so they don't make the specs very clear. I would feel more loyal to them if they had provided anything to power my looper pedal with but cheap batteries that last no longer than about an hour! Anyone who practices guitar knows that can get expensive real quick! I've been buying guitar pedals a long time so I remember when ac adapters came in the box. They still should for the price you pay!

Thank you! The power source worked well!

Just what I needed!! Thank you

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.

Muy buen adaptador, Cero ruido de tierra y el pedal wha funcionasin problema.

réponds aux attentes, fonctionne bien.

Muy buenos materiales, y su desempeño en función ha sido muy bueno.

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.
