Sony MDR-7506 Service Manual page 9

For each Mustang Micro effects model, six different settings of one particular effect param-
eter can be chosen using the MODIFY -/+ buttons (F) on the side of the unit. Five of these
consist of a middle default setting, two progressively weaker settings (- and --) and two pro-
gressively stronger settings (+ and ++). MODIFY LED color indicates effect parameter setting
in use; LED will illuminate for 10 seconds and then extinguish until any button is pressed.
To achieve an amp-only sound with no effect present, a MODIFY effect-bypass setting is
available (---).
Effects models and the parameters affected for each effect model are in the below left table. MODIFY button effect
parameter settings and their LED colors are in the below right table:

SETTING MASTER VOLUME AND EQ CONTROLS
Once amplifier and effects models are chosen, overall volume and EQ are easily adjusted. For
overall volume level, simply turn the MASTER VOLUME wheel (B) to preference (image at right).
Note that MASTER VOLUME controls instrument and overall volume only; the mix between an
instrument and a Bluetooth audio source is determined using the volume control on the external
Bluetooth device.
To adjust overall (EQ), five different settings can be chosen using the -/+ EQ buttons (D) on the
side of the unit (image below). These consist of a flat middle default setting, two progressively
darker settings (- and --) and two progressively brighter settings (+ and ++). EQ control affects
signal after an amplifier and effect are chosen. EQ LED color indicates EQ setting in use (table
below); LED will illuminate for 10 seconds and then extinguish until any button is pressed.
