On May 27th the instrument (the future Prototype II) was returned to Ekoda Strings and Ueda started to convert it into a five string cello.
TEST RESULTS [6]. (Featuring Prototype I with a different E-string.)
On May 29th the Prototype I Larsen E-string was replaced by an E-string made by Helicore, a company which produces cello E-strings at a slightly lower price than others.
There is no noticeable difference to the Larsen string – neither in material nor in sound. The nasal property is still present.
This is as far as experimenting with Prototype I will go.
The next stage will consist in testing and recording the five-string turned Eastman Prototype II, which is currently worked-on by Ueda.
