hi peeps I,myself to tone the acoustic strings many years ago I made a brass nut and a brass bridge or (you can buy them) for my Oscar Schmidt which is quite a loud guitar to begin with,they were an instant hit,brightened the sound greatly,now I bought the brass pegs just for the trio look,therefore the nut and bridge comes into contact with the strings and make the difference,the pegs may help but they look good anyway,all the best Si
