Until now there has not been any easy way to browse the wiki in any meaningful way. To address that shortcoming we've recently completed the first phase of the Portal implementation. Portals are meant to provide a way to navigate the wiki.
The first phase includes the creation of yearly Portals for each year back to 1987. Check out the 2017 Portal to get an idea of what this is all about. This page provides a list (including images) of all of the current models with links to the individual model articles.
The next step involves crafting portals for each guitar series. This remains a work in progress, but for an example of what these will look like, check out the RGA series portal. This page breaks down all the RGA models by line (i.e. Prestige, GIO, etc.), year, bridge type and more. Look for more of these series portals to be created in the weeks and months ahead.
As always, if you'd like to pitch in with this undertaking or if you have any feedback, please feel free to reach out.
