Very low output due to the metals used, sounds sh*te.
Having said that, D'addario used to make a copperwound electric bass string in the early 80's that looked & sounded really good, but they didn't sell so they were discontinued

I had a set of those. . As you say , looked and sounded great. Felt quite sticky to my fingers, so I never revisited them.
