I don't have a "standard" design for a classical guitar, a traditional Classical musician might choose one specification, while a contemporary player will make other choices.
The pictures illustrate a number of variations that have been made for different customers. Generally I would regard these instruments as being suited to those who wish to transfer from steel strings to nylon, adding extra dimensions to their range of sounds.
The technical specification is an example of one common set of choices, and I am happy to answer specific questions.
Indian Rosewood back and sides, Englemann Spruce or Cedar top, one piece Mahogany neck, Ebony fingerboard and bridge, no position markers, gold plated Gotoh tuners, Rosewood bindings with marquetry borders and marquetry purfling on front. Hiscox Liteflite case included.
