i lost my Indigo 2 cord at a show last night. will this one for the Polar fit/work?
 

This cord is basically universal. IIRC the power supply (the expensive part) on your synth is internal so you should be in good shape.

There's a version with one round side and one squared side which would work in theory but won't fit into your synth without carving at it with a razor. Basically, if it fits, you're fine. Look around your house, you may already have one - 12 bucks seems like way too much money for something that would come for free with something you'd pay 12 bucks for.

gotcha. thanks!

Although am not gigging, have found it so very helpful to use identifier tags or using a paint pen on cords identifying which belongs to each synth and perhaps that would help you in not allowing your cords to be mixed-up with the house cords or other mates where you are playing as well in home studio. A tip someone gave me that is so simple but also pragmatic and hope it helps you and anyone else reading this!

I have a friend who paints all of her wrenches pink with nail polish so that when she goes to a race no one borrows them.
