Boss PSA-120S ADAPTER  

Only after I purchased the Boss-RC-3--Loop pedal- dId I discover  it needed a power supply---NOT STATED AYWHERE ! Sure it will run on Batt. power for about 2 hrs. unaccepable IT SHOULD COME WITH THE POWER SUPPLY!

Its a plug...

This is what scared me a little. I really didn't want to have to buy batteries for my ME-70 and "compatible" adapters scared me so dispite what I read that the quality was poor I bought it anyway. After examining it closely I can say it appears to be made about as well as any other adapter I own, if not better. I have to say I am not a gigging musician; more of a studio guy, so perhaps in a road scenario it doesn't stand up as well but that could be said about anything, really.

There are 2 reasons to get this:

1. Never have to buy batteries again

2. If you use it with the ME-70 (and probably any other pedal), it shuts off the device once you cut power to it. This means you don't have to unplug the input jack. I have it hooked up to a rack mounted "rack oft switches" so I can turn it off with a quick flip. I hated the fact hat I had to plug and unplug the input chord all the time. Again for a gigging musician this is much less of an issue. Chances are you would want the battery advantage for the cordless point.

If you are a studio guy or a hobbyist, this plug makes a lot of sense. While its kind of pricey for what it is and I saw comparable "knock offs" for the price range, it just didn't make sense to risk my $$ ME-70 for a little price difference. And now I know I have MF and Boss to stand behind me stuff.

The 9-Vdc battery eater has been calmed and I'm loving it.

Hey, it provides 9 volts to my pedals the way any other adapter would, but its best feature is its trim and slim design and the positioning/placement of the plug prongs. The PSA-120S adapter when plugged into a power strip because of it design does not overhang and cover the adjacent outlet like other bulky adapters do, allowing for another PSA-120S to conveniently plug in beside each other.

I currently own 3 other PSA-120S adapters and they have performed flawlessly for well over a year.

I am continuously plugging and unplugging them into my pedals, and thus far I have had no problems with the tip or wiring on any of them. If you don't abuse them or try unplugging them from your pedal by yanking on the wire I don't see why the PSA-120S would not last you a long time.

They are a real space saver on my power strip and I would recommend them to anyone looking for the same.

The are sturdy and well constructed of heavy duty durable plastic, and the plug prongs which are molded into the plastic are sturdy and tight as well.

I think they are well worth their cost. I have purchased others which only lasted 7-8 months or the plug prongs began to loosen and ultimately failed -- and then there was the inconvenience of their bulkiness covering the adjacent pwer strip outlet. The PSA-120S is the way to go!

I like its trim and slim design and the direction it faces when pligged into my power strip, but my only negative comment about the PSA-120S is the plastic device attached to the power cord is a bit big and bulky -- I wish it could be made smaller.

The power supply has never left the practice stage, it has been plugged in to one outlet and it failed after 6 months of ownership. This is very cheaply made. I would suggest finding another power supply.

Not a good buy for the money, you have to replace it every 6 months.

Look for a better option,  this one is not good
