Relatively inexperienced player, less than 4 years. I just recently changed pickups in both of my S2 McCarty 594's. Seymour Duncan Pearly Gates in my Thinline and a set of 58/15 LT's in my DC. I noticed on both guitars that it took about 10-15 hours of playing time before my ears noticed the significant tonal change. Does anyone agree with that or are my inexperienced ears imagining this???
