I can't imagine having just one guitar. I have several, but my 'essentials' are my Martin DX1 that I take to the more crowded sessions because it is very robust and sounds amazing and the best guitar that I have ever heard to accomany melodions, I have a HD28V that I am in love with that I use where the session is not too crowded or it is a 'stage' type of club, and I have a smaller parlour size guitar that I use for writing my litte songs on. Then there are the others - permanently tuned to GADDAD etc. I don't mind lending the DX1 to most people, but the HD28V I am a bit more choosey as to who I lend it to.
