Can we learn from a guitarist? Hell yeah. Especially when it's a rhythm guitarist, and especially when it's Cory Wong.
The thing that leapt out at me is that Cory isn't a 'born genius'. He is as good as he is because he works. Hard Every day. And not just mindlessly repeating shapes. He mixes musicality into his warm ups. All of this works for us on bass too. Check it out.
