The bass is based of the actual double bass measurements, it has a 41.5 scale and a 18 inch tub.
The following steps are the different stages as the bass comes too life.
Step 8: The Head Stock
Step 9: Double Style Wash Tub Bass
(A) machine heads = 7.25
(b) Strings (Weed Wacker) = 19.99
(c) piezo pick up = 10.00
(d) tub = 6.00
Total cost = 43.24
The main reason for the enamel paint was too cover the flaws in the recycled wood.
As you already noticed I have added a pick-up inside the tub...mounted directly too the jack. I have it mounted on the neck brace just under the bridge. For better volume I will be moving the pick up directly under the bridge...but this time mounted directly too the sound board.
