    I just ordered the MTX Ultra and it is on its way and I am trying to get prepared for its arrival. It doesn’t come with a power supply and it specifies a 9V center negative power supply. I stopped in to a shop to find a power supply and the guy recommended a TrueTone One Spot. It looks like it will work but there is nothing on the box that tells me if it is center negative. Does anyone know if this will work?

    Yes, OneSpots are "Boss style" center negative.

    Thank you, I was worried because I have some older power supplies laying around and a few of them are not center negative.

    In the pedal world center negative is more common but center positive still exists. Kind of the opposite in the rest of the electronics world. You were right to check! But you're good with the OneSpot.
