I generally go with vintage frets on my basses because I'm mostly a finger style / pick player. I've been getting more into thumping and plucking and have been wondering if smaller frets could make the technique more challenging. I'm wondering the same for active vs. passive as all my basses are passive. I know there were some early players who likely were working with both so it's likely achievable, I'm just wondering if there's science behind it helping to define optimal.
