High Density / Low Density Swamp Ash on Z Series
The use of high density Swamp Ash on the bass side increases sustain, clarity and punch of the B and E strings. Low density Swamp Ash on the treble side keeps the G and D strings nice and warm sounding.
Swamp ash is a highly sought after, great sounding wood. The problem for luthiers is that it is also very inconsistent weight wise. Not only from board to board, but from one end of a board to the other! This is why you see such a variance in the weights of swamp ash basses.
Using our dual density concept we separate the dense, heavy blanks from the lightweight ones. The heavier blanks get used for bass sides only and light ones get used for the trebles. Not only does this provide the tonal benefits of the dual density system, but also all of our swamp ash basses are very consistent in weight and tone.
