There are 3 types of strings available in the market, according to the production process: 1. Uncoated. 2. Thinly coated. 3. Thick coated. Here are some of our suggestions for string selection: Uncoated strings will have a much more open sound than coated strings. However, corrosion and rust are inevitable defects. Therefore, these strings are suitable for short term use, such as professional recording, album production, and concert performances. Coated strings are a good solution to this problem, but they are inferior to uncoated strings in terms of sound. The thicker the coating, the greater the rust resistance, but also the greater the loss of tone. So for daily practice, we recommend thin coated strings. This is a good balance between tone and durability. For a guitar that is rarely played, we are only looking for durability, so the thicker the coating, the better.
