to replace the rear thumb screw to insure correct electrical
contact and pickup alignment.
C o n t r o l s . The unique Ampeg Dan Armstrong Tone
Control circuit offers incredible tonal flexibility from a single
pickup unit. A 3-position switch is used to allow
various “presets”. In the CENTER position, the TONE
control is bypassed with the signal sent from the VOLUME
control directly to the instrument output jack. In the
FORWARD position, the TONE control acts in a conven-
tional way, smoothly reducing high frequencies to a warm,
dark timbre. In the REAR position, different frequencies
are affected by the TONE control, which allows a sound
reminiscent of a half-cocked wah pedal. Good for over-
driven solos! When the TONE control is fully on (clockwise)
little effect will be heard. As the TONE control is rotated
counterclockwise, the effect of the FRONT and REAR
switch positions becomes more apparent. A bit of experi-
mentation will provide you with some interesting and useful
sounds.

carved rosewood bridge mounted to a steel bridge plate.
Small brass inserts are inlaid into the bridge, which allows
accurate intonation for string sets using an unwound “G”.
A small screw under the bridge plate mounts into a
threaded insert under the bridge to keep the bridge in
place during string replacement. This screw has been
set at the factory to be tight enough to keep the bridge in
place, but loose enough to allow adjustment when differ-
ent string gauges are used. This instrument is supplied
with light gauge strings (.010" – .046", from high to low).
If you change string gauges, you must adjust the bridge to
achieve accurate
intonation. To do so, play a harmonic at the 12th fret of the
high E string, and then fret the note at the 12th fret. If the
