So, I am struggling a bit with the tone I am getting from my cedar topped guitar, lately. It has developed what I would describe as a string buzzing sonic quality across multiple strings. I have Elixir lights on it as spec’d by Taylor and I have recently changed from a prime tone pick to a Tortex , which has helped a bit , but has not quite given me what I want to hear. I thought cedar would normally give a warmer tone , but what I am hearing is very metallic and unnatural. I understand that cedar can be over driven with aggressive strumming, but I don’t think that is what is going on here. I have thought about changing to a warmer sounding string, but I am wondering if I should be looking to some other solution. The strings are not new , nor would I say they are due for a change. Could it be something else like a loose nut ( never heard of that)? Any ideas on where to go/what to try would be appreciated. Thanks
