"I have no guitar technique"

In this quote, Warren Zevon is revealing his lack of ability or efficiency in playing the guitar. He is admitting that he does not possess the technical capabilities that are often connected with being a skilled guitarist. This could mean that he struggles with particular techniques, such as fingerpicking or strumming patterns, or that he simply does not have a strong understanding of music theory. By mentioning this, Zevon is being truthful and modest about his abilities, and perhaps acknowledging that he might not be as knowledgeable as other guitarists. It also shows that he values strategy and acknowledges its significance in playing the guitar.
