Hello Everyone, My name is Vikas i have an Grason acoustic guitar its a 4 year old guitar. Recently the guitar action got high and i was unable to play guitar. So i took the guitar to Albertos to lower the action. I don't know if he filed the guitar nut more or what he did now the guitar is producing jarred sound in the lower 3 strings and the guitar is sounding very bad. Let me know if there is any place in mumbai from where i can buy a new nut for the guitar and if i can fit the nut myself or is there any guitar repairing shop. Please suggest.. Thanks in advance I don't want to keep this guitar down. I can buy a new one but don't want to loose this one.
