I have a 2008 57 AV PBass that I love. Lightweight, resonant and sounds great. However I just can't deal with the gold anodized pickguard. Yea, I know it's original and all but after a couple months I decided I needed to change it to a more traditional tort guard. Now that it looks and feels better to me I'm wondering if I also need to add a pickguard shield underneath. The 62 tort guard is just plastic with no foil or other shielding underneath. Anyone have experience with these? Do I need one and will it make the bass quieter?
