Greetings, I love this forum, and have been browsing string threads lately. In the last couple of days, I have installed 4 new strings on my double bass. I am an "advanced amateur" orchestral player who teaches elementary DB in my home studio. I have a 2004 Shen and love it. After 5 years of playing on the same strings (Belcantos on G/D, and Helicores on A/E), I decided to "treat myself" to new strings! Decided to install them myself, since I have no problem installing my son's violin strings! Installed the G string first, a Corelli 370F. Way too bright for me, but I'll give it a couple weeks. Then I put an Evah Pirazzi Weich on my E and I am loving that!! Today I replaced the D string with Dominant Solo, and A with Belcanto Solo. So far I like both of those strings. However, I found it much more difficult to install them...had to wind/unwind from the tuning gears a couple of times. After doing that, the silks on those 2 strings started to come apart, exposing part of the inner wire and core! However, the string length from nut to bridge is just fine...but did I ruin those 2 strings? Has anyone else ever done this? (I feel pretty silly right now...but just wanted to try out some new strings, before settling in on a set of 4 of the same type.) Thanks for your input!
