I freely confess that I am guilty of ordering every possible permutation of guitar string from my favorite online dealer. There are days when the floor of my practice space is covered with spent strings and assorted clippings. The cat finds infinite entertainment value pouncing on wriggling pieces of phosphor bronze.
Today I tried a set of medium GHS Thin Core PB’s. I like them. A lot. Warm like PB strings tend to be, but also VERY easy on the fingers due to the thin, round core. They do a fine job moving the top with out so much tension to cause fatigue for my 60 year old hands. Worth checking into, IMO.
