NYXL strings are the shiznit, I need some more in my life!
I've tried most other brands but since I tried these I haven't fitted anything else to any of my bass guitars.
If someone was having difficulty deciding whether to buy a bass from me I'm fairly sure that going off on one at them would make sure I had just lost a sale.
To be fair most festivals are sailing pretty close to the wind financially, every little helps and all that.
Doesn't mean I agree with your fellow band members activities tho
