Walker Guitar Models are made up of a Style (Style B Special) + Size + Options.
Guitars are priced by Style + Options.
In this way I can offer hundreds of possible Models in a straightforward framework. Options aside, 4 Styles + 6 Sizes starts with 24 possible models. In reality, each of my guitars is a unique instrument.
Though this may seem like “too many choices” using my order guideline sheet makes it pretty straightforward decision making.
