The "Know More" section on the side here tries to persuade the reader through reasoning that this guitar is better than any other company's. It states what is unique and what makes this guitar the one you should buy.
A larger set of links at the bottom of the page can take you away from the products to information on artists, news, archives and more. This is good, as it helps find information faster.
On all the guitar pages they will have basically the same layout, but with a different background image and colour scheme. It helps you to stay familiar with how to find what you are looking for, while keeping the pages looking fresh and different.
This is using Ethos backing your product with someone who knows the subject, but also this can appeal to one's emotions, possibly getting someone to buy a more expensive guitar because their favourite musician uses it.
On this electric guitars page they show pictures of guitars from the different electric guitar series. This is a great alternative to just text, as it catches your attention and appeals you the reader more. This also helps if you are looking for a guitar with a specific look.
Noticing that the electric guitar section seems to be all about rocking out, the texture could be seen as kind of "grungy", appealing to a rocker more than a simple plain colour might.
