This is a listing of items imported in bulk for personal use. These are budget strings, but in my personal opinion, they are better than the strings sold at a certain musical instrument store. Normally set up with a Floyd Rose. The tuning stability the next day is good. They could be used without any problems as practice strings. As prices are steadily increasing recently, it is becoming rare to find good strings at a low price. It is thought to be a usable item with no issues regarding price and quality. Points to note It is generally short. The 1st string is long and the 6th string is short, so on my reverse headstock (where the 6th string is furthest away), the 6th string was too short to wind. There were no problems with standard headstocks such as Les Paul or Strat. Please understand that it cannot be used with a reverse headstock.
