..If you get a myVolts Ripcord AA840MS adapter, then it does work very well. I bought this from reading the reviews, expecting it to go straight to my model samples, but sadly it did not fit. I did get the adapter, so it works lovely, besides sitting a bit loose in the back due to the shape of the tip on the myVolts Ripcord AA840MS.
All in all, I love the myvolts Ripchords and have 3 different ones that I use with guitarpedals, volcas, and such. Solid product but do make sure the one you are getting will fit your gear!
