Clear is just like it says: Clear finish, no color.
Vintage tint, on the other hand, is clear finish with an added colored tint to approximate the yellowing that occurs on a lacquer finish over time. The actual color on any piece is a function of the tint combined with the color of the underlying wood. Darker the wood, darker the resultant finish.
On maple, vintage tint tends to look somewhat yellow.
This is my current project body, vintage tint on maple.
Here's the back, vintage tint on mahogany....
While clear looks uncolored.
This is my Jazzmaster body, clear on maple.
Note that Warmoth bodies are poly finished, not lacquered, and therefor do not yellow anywhere near that much on their own.
