I have never played an acoustic bass. Some consider an acoustic bass guitar an oxymoron. When I looked on the web for acoustic guitars I mostly found what is really a solid body guitar. Some were made to look a little acoustic but the “acoustic” body hid what was basically a 2/4 under bridge that the neck attached to. I gather that acoustic meant a piezoelectric transducer under the saddle. I wanted a real acoustic instrument. From everything I read on web it seems this guitar was the closest to performing as a true acoustic and could hold its own with other guitars. I guess to achieve this performance the guitar is ridiculously huge. Look at the last photo with it on top of a stack of two full sized radius disks.
We will see I am putting a LR Baggs active element under the saddle transducer as well.
I have the bracing finished and glued the back on the RIMs I still need to put the end wedge in so I held off gluing the top. Being able to hang the rim on a board while cutting the end wedge makes the job a little more manageable.
I have started to pick out the trim for the guitar. I am going to use black fiber bindings; I can put them on without bending them. For the top I will bend herringbone purflings. On the back I will use bwb purling. I decided on an ebony peg board veneer. I am going to put a veneer on the back of the peg board as well. I am still deciding on what to use. I am planning on picking a veneer and using it for the back pegboard, heal cap and end wedge.
I played around with a rough peg board shape. I want the strings to run straight to the nut so that dictates the shape somewhat. I included a picture of my sketch on the plans. My tuner holes are the messy Xes. I will keep the tuners the same distance from the side. So I laid the tuning holes on the sting lines and placed a dot the correct distance toward the side. Then I just drew curves to tie all of the points together.
The top bracing is a bit weird with the x-brace terminating in a massive transverse brace. It took me a bit to figure out why it was done that way. It finally dawned on me that while the guitar is oversized the bridge is not. To keep the x-brace underneath the bridge and optimally place the brace under the sound hole the X hits the transverse brace instead of the rim. I tucked them into the brace.
I used up every clamp I had to glue on the back. The back really fit well so I probably could of gotten by with a lot less. In any case I cannot see light coming into the guitar from the back seam.
The top has a 40 foot radius with the middle 4 inches of the transverse brace flat. The top came out right where I wanted it. The height off the bridge with a straightedge the is just a bit above the bridge with no frets. I had to think about that for awhile as I am building a fretless guitar. I thought about having a higher angle to compensate for the loss of the fret (.5 mm at the bridge). But then I decided the height of the string off the top was my first concern, secondly a base guitar should have a bit more action anyway. But really I have no idea what it ideal means when playing fretless. I guess I will find out.
It is HUGE!
