Pure Classic

Pure Classic

Thank you for buying the 

Pure Classic

 Transducer System for your guitar!

This system includes the four head piezo-ceramic transducer with endpin jack.

The 

Pure Classic

 Guitar System has significant advantages over saddle transducers:

Warmer sound quality

Less fret and finger noise

Well balanced individual strings

Less percussive, important for hard pickers

Don’t worry about the length of this manual; it is written great detail to help you install the 

Pure System 

for best 

possible performance. In the end the installation of the system may be easier than a saddle transducer 
installation. We want to make sure that the installation is done right the first time, so please take the time and 
follow this manual precisely.

Please familiarize yourself with the handling instructions of the supplied superglue and the supplied double side 
tape and with the disclaimer at the end of this manual. Please read through the entire manual before installation.

List of tools needed: 

Electric drill (for endpin jack mount)  

Drill bits 3/8" (10mm) and 1/2" (12mm for endpin jack mount))

Pliers or wrench for endpinjack installation

4 latex gloves (if superglue is used)

Acetone

Fine sandpaper or razorblade

Some double side adhesive carpet tape or similar 

Some duct tape or fabric tape            

Your 

Pure Classic 

includes the following hardware parts:

4 transducers with cable-harness and endpin jack

Super glue

Double side tape for removable installation

About removable vs. permanent installation of the 

Pure Classic 

and the difference in tone quality:

The pickups can be installed either permanently -- which refers to super-gluing them directly to the wood inside 
your guitar -- or removable, by using the supplied double side adhesive tape.  Of course, there is a difference in 
tone between these installation methods.

Pickups that are superglued directly to the wood will put out about 25% - 30% more volume, more bass and more 
midrange. The overall tone quality using the direct installation is probably best described as providing 
“authoritative midrange” and very fundamental bass response. Fingerstylists will like that. It is absolutely great for 
flat-picked solos, too. This way, one single tone will sound very warm and “thick”. 

On the other hand, removable installation using the double-sided adhesive tape provides a somewhat finer tone 
with more definition. It sounds slightly brighter with less midrange and less bass response. The output will still be 
sufficient and higher than most competitors’ passive pickups. Volume and bass can easily be boosted with one of 
our preamps if desired. The pickups are virtually noiseless; pre-amplification usually does not introduce noticeable 
noise.
