I've had a Gretsch Electromatic (hollow body) electric guitar for about a year now. It still has the factory strings (I have no clue what they are). A friend of mine whose played electric guitar for a long time felt that the factory strings on it were way too heavy with too much action and rather hard to bend. His preference is for Fender 150LR strings which he finds very easy to bend with much lower action. So, my question is what would you recommend and what are the advantages and disadvantages of different string types, including material, e.g. stainless vs. nickel etc.? Incidentally, I'm primarily a classical guitarist so I finger pic, which could make a difference in the type of strings I would use on my Gretsch.
