For installation of the system with no controls (battery clip only)

 

install the Amulet M preamp so that the EXT jack will be facing down 
while the instrument is being played. This assures that the battery bag 
and battery will safely sit at the bottom side of the instrument while 
playing. For Amulet M-V or M-VT systems, install the battery bag on or 
near the neck block for easy battery access. 
 
You can place the assembled system on top of the guitar to figure out 
where the best locations would be for the cable clip(s) along the side of 
the instrument with the Thumbwheel Controls installed (cover the top 
with a T-shirt or other soft cloth to prevent finish scratches).  
 
Make sure that the cable will be held securely between the controls and 
the preamp so it won’t be rattling against the side, back or top of the 
guitar (which would be picked up and  amplified), but still has enough 
slack to make sure that the connections stay secure and are not pulled 
loose. The volume board connector cable uses the larger adhesive “C” 
clips, which are shipped already attached to the cable. During the 
installation process, you can decide on the adhesive locations inside the 
guitar for these clips, and whether you will use one or both of the 
supplied large “C” clips. 
 

The system is also supplied with a single smaller “C” clip.

 This clip 

is used to hold the excess pickup cables securely inside the guitar after 
the installation is complete, and keep them from rattling around during 
your performance. An excellent way to accomplish this is to tie both 
cables together in a loose single knot, and clip the bottom part of this 
loop into the small clamp which is stuck to the middle of the back of the 
guitar, about halfway between the bridgeplate and the preamp. You can 
adjust the size of this loose loop/knot to take up any extra cable slack 
and keep the pickup wires secure.
