| Read the sticked thread near the top of the forum (just above this post, as a matter of fact) It is titled: "String FAQ - Read before posting"
There are some links there that will answer the round vs flat and nickle vs steel questions. If you still have questions, feel free to ask.
String choice is kind of a personal thing, and we can mostly just offer opinions. I like Ernie Ball standard Slinkies myself (custom gauge / heavy gauge inexpensive nickle round wounds) |
