Read Me First!
Installation of this product is a simple procedure,
but we recommend this job only if you are an
experienced repair technician.
Requirements
AG-Series pickups are designed for specific string
spacings. Be sure to select the correct pickup for
your instrument.
AG-094 or AG-125
2.125” (54mm) string spacing ±.05” (1.3mm)
.094” (2.3mm) or .125” (3.2mm) width
AGX-094 or AGX-125
2.3125” string spacing ±.05” (1.3mm)
.094” (2.3mm) or .125” (3.2mm) width
Saddle slot
Minimum saddle slot length: 2.775” (70.4mm)
Installation
Observe the following
precautions!
• Handle the pickup carefully! Do not trim the
pickup to make it fit. Mishandling may tear
the delicate foil shield, producing ground
hum or intermittent signal.
• Both the saddle and saddle slot must be flat
and square for proper pickup performance
and balance.
Mechanical factors affecting pickup
performance
• Break Angle: In order for the pickup to
perform optimally, there should be a 20°
(minimum) string break angle across the
back of the saddle.
• The 50/50 Rule: There is an important
relationship between the overall saddle
height and the bridge slot depth. We
suggest that the saddle slot depth (with
pickup installed) measures no more than
50% of the total height of the saddle. If
the slot measures more than 50% the total
height of the saddle, balance and/or output
level of the pickup may suffer.
1. Locate the wire hole
The location of the wire hole is critical to the
performance of the AG-094/AG-125 as it
determines the correct position of the piezo
elements relative the strings.
1. Locate the center of the wire hole .234” (5.9mm)
from the closest outside string. (Or center of the
closest pair of outside strings for 12-string models.)
2. Mark the location where the wire will enter the
saddle slot. Center the mark between the walls
(width) of the slot.
3. Drill a .094” hole.
4. Clear wood chips and foreign materials from the
saddle slot.
5. Carefully insert (do not bend) the pickup. The
pickup must fit loosely in the slot, without binding.
If the corners of the pickup touch the radiused ends
of the saddle slot, pickup failure could result.

2. Prepare the saddle
Organic saddles (eg, bone or ivory) are not
structurally as consistent as synthetic materials and
may not produce optimal string balance through
the pickup. Synthetic materials such as Micarta™
or Corian™ are suggested.
1. Prepare a .125” wide saddle (.094” for Narrow
Format). The bottom of the saddle must be flat.
2. Remove only enough material from the width of
the saddle to provide a sliding fit in the slot. To test
the fit, the saddle should slide easily in the slot, but
should not fall out when overturned. To maintain
your current action, the new saddle must be .048”
shorter in height than your current saddle.
3. Install the pickup
If installing the AG pickup with an optional
onboard preamp, please defer to those instructions
to complete installation.
1. Insert the pickup in the slot and then strip and tin
the wire ends.
2. Unscrew the shielding cap on the jack to expose
the solder terminals. Thread the pickup wire through
the shielding cap.
3. Solder the insulated pickup “hot” wire to the Tip
terminal and the ground wire to the Shield tab.
4. Gently tighten the strain relief and refasten the
shielding cap to the jack.
4. Endpin jack
Install the endpin jack per Switchjack Installation
Guide.
