How do they work?
The color-change reaction is very dependent on the ambient room temperature. They were developed to react best on stage or similar warm environments. LingerPrints® will remain black until they reach the reaction temperature at 84ºF and above. Your hands will warm the neck the longer you play and LingerPrints® will react faster the closer they get to the reaction temperature. If the ambient temperature in the room exceeds the reaction temperature, the decals will change colors without touching them. For the best results you would want to use them in a setting that is as close to the reaction temperature as possible (under 84°F) and the heat from your hand will cause them to change color almost instantly.
Are they easy to install?
Installation is as easy as peel and stick and should only take about 20 minutes. You can apply them without even removing your strings (you do have to loosen them).
What guitars are compatible?
LingerPrints® will fit guitars with a 25.5" scale length. To figure out the scale length, measure the length of the string starting at the nut and ending at the bridge. They are designed as "one-size-fits-all" due to the variance of fret size and spacing on different guitars.
Are they removable?
Yes, LingerPrints® are removable, but they cannot be reused once applied. To remove, pick at a corner with your fingernail and peel up slowly. The clear top layer may separate, leaving just the backing and adhesive on the fretboard. If that happens, just pick and peel. If any adhesive is left over on the fretboard, we recommend using Goo Gone or Naptha and a cotton cloth - Do not use acetone or nail polish remover! Once the fretboard is clean, you will want to oil it since the solvent may have dried it out.
What else is included?
The package also includes 2 rectangles which are intended to cover the space on the fretboard beyond the highest fret, or fitting an irregular fret that is outside of the standard measurements. There may be cutting required.
