Man this guitar looks awesome, love the painted headstock too.

I’ve never tried a metal pickguard. Does it reduce the high end? I’ve had brass open pickup covers on single coils before and it noticeably reduced the high end. I thought it wouldn’t because they were open, but I was wrong about that.

Try one! I dig em no worse than insulating copper foil IMO.

I queried the Oracle on this one, and the AI replied as expected:

It's true that an aluminum guitar pickguard can provide shielding, and importantly, it does so without significantly interfering with a guitar pickup's magnetic fields. Here's a breakdown:

• Shielding:
  • Aluminum is a conductive material, meaning it can help block electromagnetic interference (EMI) and radio frequency interference (RFI). This interference can cause unwanted hum and noise in a guitar's signal.
    
    
  • By placing an aluminum shield (either a full pickguard or a sheet of aluminum adhered to the underside of a pickguard) over the guitar's electronics, you create a barrier that helps to divert this interference away from the sensitive components.
    
• Magnetic Fields:
  • Guitar pickups work by sensing changes in the magnetic field created by the vibrating strings.
  • Aluminum is non-ferrous, meaning it's not strongly attracted to magnets. Therefore, it doesn't significantly disrupt the magnetic field generated by the pickups.
    
    
  • This is a crucial point: you want to shield the electronics from unwanted interference, but you don't want to block the magnetic field that allows the pickups to function.
• Practical Considerations:
  • While aluminum provides effective shielding, copper is often considered superior for this purpose due to its higher conductivity.
  • For optimal shielding, it's essential to ensure that the shielding is properly grounded. This creates a path for the diverted interference to flow to ground.

In summary, an aluminum guitar pickguard or shield is a valid way to reduce unwanted noise in a guitar's signal without negatively impacting the pickup's magnetic field.
