I would also just like to add my praise for Rotosound service. A couple of years ago I ordered a number of various sets from a local shop (now gone) by phone. They said that they would need to order them. Fine I would pick up next Monday and paid by credit card up front. Cutting it short the shop kept making excuses say Rotosound were out of stock. Contacted Roto who said they hadn't had the order. I lost it a bit and emailed all the addresses on their site moaning that I could get the strings in three days from the states but not buy locally. Next thing I know is I'm getting calls from Roto people all being very positive and helpfull. Can't remember who, it may have been Jason took my address. Next day in the post I receive the complete order of strings free of charge.
I have always used Roto's and will continue to do so. I've only ever had one slightly iffy D string, but didn't complain as they had been so good before. I still haven't used all the strings they sent yet
Keep it up Rotosound
