OK - two things as a result of my recent purchase of an NS CR5 EUB, with which I hope somebody can help me out, as I am now a "newbie" to all this - treat me gently! So firstly, the G string looks and feels different to the others and has a blue "binding" which actually extends over the bridge - is this a bad thing? Should I take it up with the shop were I bought it? Secondly, I do quite like the sound of the other four strings and from the website it says they are D'Addario Flatwound double bass strings - but nothing more specific? But I would like to ask what sets of strings I should be looking at buying - I mean I got the piezo-only version - no magnetic pickups; but are there particular sets for EUB that sound better or can I go for any set? I have looked at Web Sites and have seen D'Addario Helicores, but would they be OK for my EUB? ( I will be looking for good pizz sound only really.) Or will only certain sorts of set sound any good? Thanks for any help!
