I've spent timing seaching the forum for answers and have come up blanks. My questions involve the process of zeroing-in on one's favorite string set. My question is not genre related I don't believe so, its length will hopefully apply to many players. FWIW, I play pizz Jazz, blues, swing and Pop. I'm a newbie. My ES-1 had Jargar's. Based on this Forum I bought Pirastro Obligato's and dig them. But....maybe I'd like Garbo's better or Thomastik Weich's, or Corelli's? How do I know w/o spending $ 240, $ 125 and $ 100, keeping in mind I just invested $ 99. I notice some Garbo's on Ebay. The seller say's "they're 3 months old, lot's of life left. Cheap oppty to see if they're right for you". You guys agree? This brings up another question: do strings suffer from detune/remove/reinstall? To complicate matters, I notice some folks here like the D & G of this set, the E & A from that set. I'd hate to buy the G Corelli for $ 35 when the x-brand G is better suited to my y-brand D. Ok, I'll shut up now.
