amp) end, this allows the shielding to remain in place while breaking the ground current flow that is the cause for inducing hum into
the signal carrying pair of conductors. Now, the one thing that complicates this is that at very high (radio) frequencies, ground is not
“really” ground, so additional techniques are incorporated within this network that allows 2 functional grounding spectrums within the
same network, providing added RFI (radio frequency interference) rejection. The general rule is to start with pin 1 lifted, and if there
is noise, try connecting it. It should also be noted that there are a lot of other possible causes for noise, this switch is often a solution
for ground loop noise between the PA and the bass amp.
