I have tried most of the fingerboard oils out there, including some that you can't find at any regular instrument dealers. This one is my favorite by far. The result is shinier and the wood looks deeper and more lively than with any other oils I've tried. The final result looks almost like that wood has gotten an ultra thin layer of laquer. Very, very beautiful. I've used this oil with excellent results on ebony and rosewood.
I also like the fact that this oil does not smell of anything. I've had some less than satisfactory results with other oils that seemingly smelled nice but reacted with the wood (or maybe some earlier applied oils) and turned out smelling very nasty.
Top ratings, highly recommended!!!
