I have never put a treble bleed into a bass. I don't think I have seen one either. I have read about a "G&L" treble bleed (a 200pF cap with no resistor), but my G&L ASAT bass didn't have one. I haven't seen one on a Jazz or Precision either. Which raises a question for me about whether you need a treble bleed on a bass? It occurred to me that there may not be that much treble to bleed off in the first place. Curious what the experience of others has been?
