"Cosmique" bass bar

In these pictures, you see my bass bar "cosmique" I've made since 1992. My inspiration comes from an American red elm whose branches unfold in the sky to collect the most energy from the cosmos, that's why his name comes from the mythological tradition "cosmic tree". This type of bass bar is very effective. It increases the depth of low pitch sound and allows an equal balance and timber of 4-5 string.
