Capo recommendations.

I was looking at the Nordic essentials one on Amazon, it mentions bass. It’s for a 5 string E to C tuned instrument.

Never used a capo on a bass. It's handy on a guitar as it enables you to use your preferred chord voicings/shapes in any key, or most at any rate. I use a Shubb for that. Don't know if they make one for bass, but if they do, it'll be worth a look.
