For those looking to brighten the tone of the board a bit - this upgrade adds our cloth layers to the inside of the keyboard against the back of the PCB and acts as an amplifier and eq for the sound of the board - making the mid tones brighter and more pronounced.

We do not use cheap masking tape or other gimmicks - we use a specially designed cloth tape that is completely residue free!  

For most boards with aluminum or plastic cases, the color does not matter. For those with acrylic or partially transparent cases - you can choose black or white to match the tone of your build.

Do not add this if you are choosing to use a silent switch - it will do nothing.
