I was looking for a pickup change in my G&L Legacy american and I sumwhat fell in love with emg single coil pups

Tone wise I would like to know peoples opinion, this guitar will be playing alot of cleans and sometimes be driven with alot of gain throught my fender tube amp
I don't mind having to change batteries

wondering peoples opinion on this pup change

NO i do NOT want other pup suggestions just want to know advantages and disadvantages!

I enjoy the EMG SA. It has a really good clean/overdriven tone
