Washburn built the C40-A-U as part of its Classical Series, positioning it to serve both dedicated classical and flamenco players as well as beginners approaching the instrument for the first time. It sat within a line designed around the specific demands of fingerstyle technique, where wider string spacing is a functional necessity rather than a preference.
The guitar was constructed with a spruce top and mahogany neck, back, and sides, with quarter-sawn Sitka spruce bracing. The mosaic rosette provided visual detail consistent with classical convention. A 52mm nut width and 650mm scale length reflect standard classical guitar geometry, accommodating the hand positions required for traditional fingerstyle technique. The Graphtech Nubone nut, engineered wood fretboard, and gold hardware completed the specification, with a Graphtech alternative bridge saddle and classical-style tuners. The instrument shipped strung with D'Addario EJ46 ProArte Hard Tension nylon strings, and carried a gloss natural finish.
Owners sourcing replacement parts — including saddle blanks, nut blanks, or classical tuning machines — should confirm dimensions against the 52mm nut width and 650mm scale before ordering. A qualified luthier or guitar technician can advise on setup adjustments and compatible replacement hardware for this instrument.
STRAIGHT TALK
What Stands Out
Keep In Mind
From the people who own them
Nothing in The Vault is for sale. These records exist so the instruments stay documented after the manufacturer moves on — and the most useful part of that record is what owners add to it.
Owner photos
Put yours on the record.
The catalog shot showed one finish, under one light, a long time ago. Yours has been played. Photos from owners are what the next person finds when they are trying to identify a part, match a finish, or work out whether the one they just bought is really what the seller said it was.
What do you know about this one?
Specs only go so far. What actually fits, what breaks first, what the factory got right and what everyone ends up changing — that lives with the people who own them, not in a datasheet. Post what you know and it stays on this page for whoever comes looking next.
