NOTE: These descriptions of the way the controls operate are 
based on having the controls mounted on the right side of the 
soundhole, so they are visible to the right-handed player. The 
controls can also be mounted on the left side of the soundhole if 
desired, and doing so will reverse the positions of the controls, 
as well as their operation (i.e. rotating the volume thumbwheel 
towards the neck on this type of installation will increase the 
volume). 

The LED battery indicator will glow very dimly during operation, and 
when the battery voltage drops to the point where it needs to be 
replaced, the LED will flash brightly at 1 second intervals, alerting you 
that you have a few hours or so to replace the battery without 
compromising the audio performance of the system. The system will 
operate at peak performance for 100+ hours (with a standard alkaline 
battery) before the battery needs to be changed. 
 

AMULET M-VT

  This option includes all the features of the AMULET M-V 

option, and adds a tone control thumbwheel as well.  When rotated 
completely to the right (towards the bridge) the control allows the full 
range sound of the transducers to come through. When rotated to the left 
(towards the neck of the instrument) the upper frequencies are gradually 
reduced, allowing you to make any desired tonal mix right from your 
instrument. The thumbwheel control is designed to make subtle changes 
to the upper frequencies for the first half of the rotation to allow for more 
precise control, and makes increasingly larger changes for deeper 
sculpting of the tone in the second half of the rotation. 

NOTE: When you unplug the cable from an M-V or M-VT 
system, you will notice that the LED battery indicator will blink for 
a few seconds after being unplugged. This is normal, and shows 
that the voltages inside are powering down and the system is 
shutting off. It is recommended that you make sure that the 
volume thumbwheel is set to a lower (or off) position when 
plugging into an amplifier and then adjusting to the desired level 
to avoid any unpleasant surprises.
