Ground Balance switch ( Track/Fix/Pinpoint )
When operating in Disc mode, the
Sovereign GT
uses digital filtering to
compensate for ground effects and the Track / Fix / Pinpoint function is disabled
So does this mean that when one hunts in Disc mode there is no need to ground balance, or does one have to first ground balance in All Metal mode and then switch to Disc?
