Cleartone Treated Acoustic 80/20
All Cleartone Acoustic 80/20 Strings are MADE IN USA at our Bountiful Utah factory using only the finest US-sourced 
wrapped wire around a high-carbon hex core.

We wind our strings under super high tensions using proprietary winding methods and core-to-wrap ratios which creates 
a denser, better sounding string with enhanced tuning stability.

Lastly, we add our multi-patented award winning treatment which is scientifically proven to increase your guitar's 
volume and sustain by up to 36% & 48% respectively.

Your acoustic guitar will never be quite the same. Cleartone acoustic strings start off 
with premium 80/20 bronze construction. The award winning and patented Cleartone 
Treatment is next. At only one micron thin, there is no flaking, no slippery feel or 
dampened tone. All strings in a set feature the Cleartone Treatment for long life 
and pure tone without compromises. 

  

Thunder-reds is a set made with three different types of synthetic elastomer. In the third and 
fourth strings, the density of the elastomeric material is also increased by adding micronized 
metal copper powder during the extrusion phase.
This technological solution allows for the same working tension to have smaller diameters, greater 
volume and sustain than any type of polyurethane and silicone rubber strings available on the market. 
The Thunder-reds ensure fast and stable intonation. Thanks to the metallic powder there is also a great 
slipperiness of the fingers on the strings.

String color: dark burnt red

This set is characterized by a different construction system than usual, which uses a special aerospace-grade 
multifilament instead of the common nylon multifilament. Varnished copper is used for the coating, which is 
hypoallergenic and less noisy under the fingers.

Pure copper replaces stiffer steel, nickel and phosphor bronze: these materials have a lower specific weight 
than natural copper. The higher the specific weight the better the acoustic performance
