WORKING ON PROTOTYPE I
In order to deal with the above mentioned problems the following measures were taken:
– The sound post was slightly moved.
– The bridge was made slightly thinner.
– The bridge was slightly carved in order to lower the E-string and facilitate string changes from the neighboring A-string. The fingerboard was not changed for now, as this would have required a rather lengthy process.
– A wolf-killer (7 grams) was equipped.
Trying to improve sound quality further, E- strings from different makers were ordered. (Jargar, Helicore.)
The presently equipped tailpiece with its rather big and heavy adjusters also might be a possible source of sound loss.
Equipping smaller adjusters is quite expensive and still could account for some acoustic loss. Therefore it was agreed to try equipping fine-tuning pegs, which could eliminate the need for tailpiece adjusters.
(Picture 12: The tailpiece, fine-adjusters and the wolf-killer, mounted on the G-string (2nd string from the left).
TEST RESULTS [2] (Featuring the present tailpiece and wolf-killer.)
– String changes onto upper strings present no problems anymore.
– Sound quality of E- and A-string became more similar; however, the slightly nasal character of the E-string is still present.
– Wolf is reduced but still present.
