during installation, and use a strip of masking 

tape to stick the piezo pickup cable inside the 

guitar to a near top brace, as strain relief.
The saddle will sit higher now that the piezo is 

installed. For proper playing action, remove some 

material from the saddle. Use double side tape to 

fixate sanding paper to a 
completely flat surface and sand off enough 

material from the bottom of the saddle to match 

your playing requirement. Always check that the 

bottom of the saddle stays flat!

4. Endpin Mounting

After drilling the 12 m hole in the guitars end 

block, start from inside the guitar, slip the pre-

amps endpin through the endpin hole and prese-

lect the correct position with the hex counter nut 

inside the guitar.  

Then fix the endpin finally with the second 

hex nut from the outside, pushing an allen key 

through the hole in the thread for use as lock 

against twisting. When the endpin is safely fixed, 

screw on the strap-button.
Now plug the piezo pickup connector into the 

piezo socket of the endpin, there should be an au-

dible „click“, to make sure it sits firmly. The internal 

microphone is best pointed towards the back 

of the guitar. Experimentation may yield better 

results with your specific instrument though.

5. Test Run

Before fixing the battery pouch, it is best to do a 

test run. Connect the battery pins to the connec-

tor of the 

AK15 plus

 system.  

Now connect the soundhole control unit with the 

small connector.

You can then connect the output jack to an am-

plifier. Plugging the jack into the endpin socket 

closes the circuit and switches on the 

AK15 plus

 

system, without jack there is no battery power 

consumption. Even when not playing, the system 

will lose battery power when a jack plug is con-

nected. Only plug in when you want to use the 

pickup system.

The factory setting of the internal microphone 

trim pot will be suitable for the vast majority of 

guitars, so in most cases, there is no correction 

necessary. 

Factory settings:

Piezo: +10dB  

Microphone: +10dB 
 

Check the sound of the piezo pickup first and 

listen if all strings sound equally loud. Imbalance 

in string volumes should be addressed by a 

luthier, or follow the tips in the trouble shooting 

section. Now add microphone signal by turning 

the Mic control. Tapping the top will let you hear 

the microphone signal very easily. Sounds good? 

Go to the next step.

5. Battery Pouch Installation

The battery pouch has a Velcro strip on the 

backside.
Peel the masking tape off the Dual-lock™ (tape) 

and glue it to the neck block or the upper bout of 

the guitar. Make sure the gluing surface is flat and 

clean. Many tone woods contain natural oils, and 

the gluing surface needs to be made grease free 

before gluing the Dual Lock™. Then attach firmly 

the battery bag to the Dual-lock™. Connect the 

battery contacts from the endpin preamp with a 

fresh battery and put it in the pouch.
Please consider:
You have several options regarding the position 

of the battery pouch, each of them may be a 

compromise, but the aim must be to combine 

easy access with a firm position of battery and 

battery-pouch. The cross braces of the upper 

bout inside the guitar may be used as additional 

support against gravitational force.
Whatever position you choose: You will have to 

loosen or even remove the strings, when a battery 

change is necessary.
Note: 
The 

AK15 plus

 system is not made for ‚micro-

phone-only‘ performance! You will find a surpris-

ingly warm yet strong and clear tone from the 

piezo due to a suitable electronic environment. 

The microphone will add definition, and authen-

ticity as well as an acoustic ambience, which 

makes the sound more natural. Too much micro-

phone signal however will make the tone ‚hollow‘ 

and can cause feedback. The piezo at full volume 

may make microphone use impractical. All this 

has been experienced without using a feedback
