My bass bridge did NOT require shims, so I’ve simply pressed into "G" string side's eye slot. Are shims required for some reason?

DB-1 shims are definitely not required, if the sensor is snug in the eye slot already- in fact, you don’t want to risk cracking the sensor by increasing the pressure in the eye slot.

As long as the sensor is fitting snugly and holds up to your style of play (i.e. if you spin the bass or not) you can skip the shims.
