I had a set of of the 5 string flatwound delivered on Monday the 11th Jan', put hem on,,,,,,,,,,B string dead and un tuneable, E string dead. Called Strings direct, was promised replacements, still waitin ,
Used almost every set of strings available over 45 years of playing, and i have to say these are the worst i have ever tried, may have well used wool!!.
Do yourself a favour, stay away from Picato, Fender flat wounds are cheaper and better, pity they don't do 5 string sets.
