reference soundboard

Here you have my reference soundboard. Thats what I use when I calibrate my soundboards. I use it to compare stiffness and weight.
The numbers on it are imperial, so 88 means .088". Its a relatively soft and light piece of spruce from Switzerland. So normally my soundboards end up being a bit thinner (.084" typically)
The soundboard has a rosette installed and weighs 120grams
