About this design
I'm on a Permanent Bass Line is the ultimate flex for boomers who refuse to turn down the volume or turn up the dial on boring. This groovy 70s design channels the golden era of funk, soul, and unapologetic vibes—wrapped in a vibrant purple and yellow gradient that screams vintage concert tee energy. The musical note icon ties it all together, giving you that authentic retro look without the mustard stains or water damage. Whether you're actually keeping the bass line permanent or just acting like you are, this design says you're still the coolest person in any room. Premium quality ensures your permanent bass line stays looking fresh, not faded.
