I nearly joined a Stranglers tribute band about a year ago but it was too far away unfortunately, but I have managed to learn a few of their songs such as Peaches, No More Heroes, and Nice n Sleazy, etc, the hardest part I found was getting JJ's tone, but I managed to get reasonably close, I think? 🤔
Go for it, JJ's bass lines are great fun to play, and if I can do it, I'm sure you can. 👍
