I had seen a Upright Wash Tub Bass being played on You-tube, and said to myself...gee I would like to own one of those. So I researched around the internet and found a set of plan similar to the bass I seen on You-tube ( http://dennishavlena.com/db.htm ).
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 1: Step1
This tub is 18" round x 10" deep
Step 2: Anchors away!
Here I used hardwood blocks 1.5 x 1 for sound board anchors.
Step 3: Sound board
This is the sound board in different stages.
Step 4: Preparing the Neck
The neck consists of red and white oar, laminated (2.5 x 2.5)
Step 5: Choosing a bridge and tail piece
Here I inserted the neck brace for the tub.
Step 7: Neck Mounted
Here is the neck mounted too the tub.
Step 8: The Head Stock
If you look hard enough (sorry for the glare) you will notice that I hand painted the neck too resemble sewer pipes, I also wanted the head stock too match, so I came up the the idea of creating a shut off valve.
Step 9: Double Style Wash Tub Bass
Well after everything was done and parts bought...the final cost
(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.
