Strings by Evah Pirazzi (Gold) is my latest new favourite! It is a little pricey compared to other strings but its sound is fantastic! They are also quite durable! Buy it when Gramercy has a sale!
The G string is Gold, D is Sterling silver, A is Aluminium and E is stainless steel. G string being gold, gives a mellow, rich and warm tone. E being stainless steel isn't too bad. The tone is still sweet. I like the tension on all strings and the sound comes out easily.
