To put some flesh on the bones (or tofu on the celery...)
For me a change is as good as a rest. I find playing different instruments really inspiring.
If you have several basses a new one might not make a lot of difference. But if you only have one, get one that's really distinct from what you have. A Talman or Harley Benton shouldn't break the bank and giving it a setup (if needed) is part of making it our own.
I've been playing almost daily all through lockdown, sometimes for hours, sometimes just for a bit. Regularly changing bass, but for about six weeks I've just been playing my Flea Jazz.
This thread inspired me to swap to my Jag SS, and I played Schools Out right through for the first time aside from a couple of changes at the end (I've been learning it today...)
