Hi there, new to the forum and to the guitar

Looking for advice, i have been learning on a very cheap guitar and getting there slow but sure , fingers were very sore to start with , then i was past the painful bit

My cousin (good guy) has given me a Yamaha sg but the strings on that are more painful on the fingers than the cheap one(johnstone)

I don't know what make any of the strings are but i want to change the stings on the SG , is there a "soft" string i can buy , can you guys give me any advice

the thiner the strings the lower the action.
buy 08 or 09 strings.
Also the problem might be the guitar itself as some of them have higher action than other ones..
Good luck =)
hands down.
