I guess I'm somewhere in 3. I can usually find my way around in things I hear. But I'm not a very good fingerpicker, much less arranger of such, don't learn them by ear. Usually even a slightly wrong tab or standard note (many classical things published with both contain errors in one or both is worth grabbing, saves me time. I'm good at finding cheap but not-too-cheap ways to exploit the fretboard, I think, all those novelties.
