Once the optimum installation position has
been decided, you can prepare to attach the
pickup. However, the distance between the
string and the pickup’s magnetic yoke is ex-
tremely important.
Since the height of the pickup’s magnetic yokes
cannot be adjusted individually, the pickup posi-
tion, the pickup’s overall height, and string height,
can be adjusted to meet the conditions necessary
for optimum string/pickup clearance.
The distance between the top of the pickup’s
magnetic yokes and the bottom of each string
should be about 1-2mm (0.04"-0.08") when each
string is fretted at the highest note on the neck. The
distance between the pickup and the bottom of the
strings can be set to less than 1mm (0.04") as long
as the strings do not touch the pickup when the
bass is played. However, as long as other strings
can be set to a height of 2.0mm (0.08") or less, try
to set the E and B strings between 1.5 (0.06") and
2.0mm (0.08").
Also, the output level for each of the magnetic
pickups is fairly different so after the divided
pickup has been attached make sure you set Input
Gain each strings with the Guitar MIDI Converter.
The chart below lists the optimum string/pickup
distance and G50 Input Gain Settings for average
bass guitars. Use the chart as a reference when
setting up your pickup.

Use the supplied clearance gauge (1mm (0.04")
thick) to check pickup clearance. Put two gauges
together to check for a clearance of 2mm (0.08").
■ First, make sure the truss rod and string
height are properly adjusted, then tune the
strings to their normal pitch.
■ Determine the optimum method of attach-
ing the divided pickup.
Refer to the “Select the Method of Installa-
tion” section on page 5, and determine the
optimum method of attachment in regards to
the attachment position, materials, type of
body, playing requirements, etc.
■ Use the supplied suction cups to tempo-
rarily attach the Controller to the body so
that it doesn’t get in the way while attach-
ing the Divided Pickup.
