Saddle is critical to transferring string vibration/energy to cone!
Note the relatively low height of the maple saddle which results in less than
ideal string tension and does not maximize the load on the cone. Saddles
with an ebony or synthetic cap (e.g. ebonex) are harder and more
consistent than the maple saddle used here and improve transfer
of string vibration to the cone resulting in better sound.
3/8” or 7/16” from underside of strings. Low action makes it difficult
or impossible to use dobro capo!

Remember – it’s not all about the parts! Attention to detail is critical.
Assuming a professional set up costs around $225, it’s around $75
for parts and $150 for knowing how to put them together!
Regal before modifications – think of the cone as a speaker which
operates most efficiently when it receives maximum energy via
string vibrations. Both the height and composition of the saddle
play a critical role in “loading” the cone.
Notice that the soundwell (made of plywood) on this
guitar was delaminating
results in less-than-ideal playability and responsiveness;
action best described as “mushy”
process is not the most pleasant experience. Sanding down a bone
nut creates a strong odor which is unmistakable! It’s a time
consuming process to get just the right fit for a bone nut!
factor! The next step in the process is cutting string slots.
Cutting a good string slot is not as easy as it might seem! Attention
to detail is absolutely critical; requires “know how” and the
right set of tools
consistent wood than the original maple saddle. Improved height
dramatically increases angle/tension of strings going to the
bridge which effectively “loads” the cone
be in a relaxed state, and sit on the internal ledge of the guitar
without being too snug – and that each of the spider legs lay
perfectly flat on the cone. The edges of this guitar had to be
routed in order to fit the Quarterman cone!
Results are vastly improved playability and responsiveness, as well
as significant improvements in volume & tone, especially
clarity and definition of notes
