Product Reviews for Newtone Acoustic Guitar Master Class Double Wound, .013 - .056, DWMC-H
Newtone Acoustic Guitar Master Class Double Wound, .013 - .056, DWMC-HW. C. BidwellApril 21, 2010These strings in the 56-13 range which for most US persons would be mediums. Newtone can't tell you the tensions as they don't know. I asked to find out. I loved the sound but found that within the short period of 10 days the neck relief on my prized Martin was increased dramatically. I had always used MSP-4200's with no affect at all. I removed the newtones and the neck immediately returned to normal. These should be rated extra heavy tension and also come with a guitar neck warning. They don't seem that hard but the neck didn't lie. I would not even try them again.
