Question: Is this an universal voltage adaptor? 110-240v
Document: I buy this adaptor for my fender amp, it work good, it looks a like that one in the picture but its not the same, it has a most cuadrangular style
This adaptor is good. I do feel the cable seems a little bit fragile. Just be careful when you handle it and I guess it will be OK
what can I say? this is an AC adaptor that works just fine. you plug it in and it works....without problems. goes very well with my Wah Wah petal which I love.
This adaptor (I got two of them) works well with the two guitar pedals I have. The chord is a reasonable length, and the product seems well made.
After years of owning a CryBaby, I'm glad I finally got this adaptor. No more fiddling with empty batteries, just plug the stuff et voil&agrave;!
I put this rating cuz its is a good item but I don't if the price was right to the item cuz its very simple adaptor but well its fine I'm happy so :D
This adaptor, in combination with the Visual Sound One Spot Multi-Plug 5 Cable, works like a charm. Easy affordable option to power up your pedals and accessories.
i got this adaptor to power my pedal board. i just use a tube screamer and a cry baby. the power supply i had made the way pedal hum like crazy. this power supply gets the pedals up and going and there is no noticable hum from the wah pedal.
Purchased this adaptor for my Kirk Hammett &#34;wah wah&#34; effects pedal. I understand the 9 volt batteries expend quickly in this unit. Therefore, the purchase was justified. Good Quality OEM. Happy, Happy, Happy !
I believe in OEM products and this is the one dunlop designated for the Crybaby Wah. It saves you from having to remove the bottom plate for battery changes and Wah's go through batteries. Some prefer the sound of battery power, but I find the tone of the adaptor power to my liking. This is the way that I chose to go and I have no regrets with the solid build, performance, convenience, and sound quality.
Answer: This is a direct plug-in Class 2 transformer: I/P 120VAC 60 Hz 7W - O/P 9V DC 200mA are the exact specifications. Regular barrel connector/input with negative center, for use with Dunlop, MXR or Boss type pedals. May work with other brands with the same specs as well. Hope this helps.
