1) Lay the pickup upside down on a flat surface. Locate the two pairs of solder pads
that the battery clips will be mounted to.
2) Press the mounting tabs on the bottom of the battery clips into the appropriate holes
in the PCB that serves as the bottom cover. Be sure that the dimpled tabs that contact
the battery are both oriented toward the outside edges of the pickup (refer to Fig.4).
Figure 4
3) Tin the solder iron tip and lay it on the inside bottom of one of the clips.
Heat the clip at one end until you are able to smoothly flow solder in between the clip
and the solder pad. Move the soldering iron to the other end of the clip and solder
again. Repeat the process for the second clip.
4) Check your solder job, all joints should look smooth and shiny (not lumpy and
gray). These solder joints are all that is mechanically holding the battery clips in place.
5) It is optional to cut the 9-volt battery holder off – your choice.
6) Installation of the pickup into the guitar is the same as either of the two previously
described methods, depending on whether you desire a permanent or non-permanent
installation of the end-pin jack.
When to Change to Battery
With hard plucking of notes, you will notice distortion on the attack of the note.
When this occurs, your battery is starting to get low. At this point, you’ll get at least 20
hours of use before it dies completely (four with the “N” battery). However, you should
change the battery at this point in order to preserve the great tone of the pickup.
keep in mind that the “N” battery clips are secured to the PCB by the solder joint
only. Not to overly stress this point, but please take care when changing the
battery.

Installing the end pin jack, pickup and battery
Tools you will need:
1/2" Open End Wrench
3/32" Allen Wrench
#2 Phillips screwdriver
String winder (optional)
Small lint-free cloth
Rubbing alcohol
1) Remove the strap button, small dress hex nut, and small dress washer from the
female jack; and then remove the black plastic sleeve.
2) From the inside (cable side) of the guitar, keep the large hex nut, large dress washer
and star washer on the interior side of the jack and slide it through the end pin hole.
The jack should protrude from the outside surface between 5/16" and 11/32". If it is
not within this range, it must be removed and the position of the large hex nut adjusted
accordingly.
3) Install the small dress washer and the smaller hex nut. Hold the jack in place with
the allen wrench and use the 1/2" open end wrench to tighten the nut.
4) Screw on the strap button and hand tighten.
5) Clean the neck block to ensure that it’s free from sawdust, oils or any debris –
this can be done with a cloth moistened with rubbing alcohol (be careful not to get any
alcohol on the finish of your guitar).
6) After the alcohol is dry, apply one half of the Velcro® to the neck block where you
wish to affix the battery holder.
7) Insert both the battery holder (with the battery in the clip) and the pickup into the
soundhole.
8) Stick the battery holder to the Velcro installed in step 2.
9) On the pickup unit itself, make sure that the clamps are open wide enough to accept
the soundboard.
10) Slide the pickup into place on the neck-side of the soundhole.
11) Tighten the screws to clap securely (warning: over-tightening can compress the foam
padding and mar your guitar top).
12) Reinstall strings and plug in a standard 1/4" guitar cable to the end pin jack and
you’re done.
13) Make great music!
Installation (Using “N” Battery)
By installing the “N” battery clips, the Mag Mic becomes a single, integrated unit for
the ultimate in portability. However, this entails some compromises. Battery life is
severely limited: you’ll get 50 hours with an “N” battery as opposed to 450 with a
standard 9 volt. Also, when inserting an “N” battery, you must ensure that it’s
polarized correctly. The positive end of the battery must be oriented toward the “plus”
symbol next to the microphone on the underside of the pickup (refer to Fig.4).
Installing the “N” battery clips is a tricky process and requires high-level soldering
abilities and a good quality iron with the correct tip. It is essential that the work be
done properly. Even when done perfectly, the clip will still not stand much abuse.
It is advisable that care be used when installing and changing batteries. If you’re not
entirely confident that you posses these abilities, please have this procedure done by
a qualified electronics technician. Here are the steps:
