“Great service! 
I have been impressed with the quality of the items I've received (especially the fretboards). You've been very helpful with some unusual builds (the suggestion to order a bass fretboard slotted from both ends for two short-scale necks was brilliant). I was very surprised at how quickly I received an order of custom-length truss rods. You have a very happy customer."

Kerfing, Back

Also known as ‘linings’. Unless you use tantalones (used on some classical guitars), you will need kerfing. The ‘small sized’ kerfing is only for mandolins and ukuleles.
