Can you do pinch harmonics on a bass?
Yes, pinch harmonics, or Artificial Harmonics are possible.
How do I get artificial harmonics?
To produce an artificial harmonic, hold down a note on the neck with one finger of the non-dominant hand and use another finger to lightly touch a point on the string that is an integer divisor of its vibrational length. Then pluck the side of the string that's closer to the bridge.
