Back brace...


The back brace is on.

My brace is different from most, if not all. I don't use a spruce brace with the grain orientation opposite that of the back, I use a maple brace with the grain oriented in the same direction as the back. This makes a very stable flat-back bass since the back and the brace can move together with changes in humidity. I've been making backs like this since 2001 and it works very well.

When I glue the brace on, I induce an arch in the back -- and I am now shaping the ribs (where the back is joined -- called the "rib plane") to induce more arch, so there is a significant arch in the back -- a good thing as it is stronger and can therefore be lighter.
