The tongue of the fingerboard of this Martin Eric Clapton signature model has lifted off. The treble side of the fingerboard has lifted significantly while the bass side has only lifted slightly. The tongue had been glued down unsuccessfully. I suspect the wrong type of glue was used thus the lifting again. The residual glue was carefully removed to ensure good adhesion and contact.

As the treble side has lifted more than the bass side, the tongue of the fingerboard was heated to flatten the "curl". Once the ebony has stabilized, the fingerboard is clamped down.

The clamps are removed and the tongue of the fingerboard is seated firmly on the top of the guitar.

The last 3 frets were lightly dressed to eliminate fret buzz and the guitar is strung.
