Scalloped frets are really good when playing fast peices, I also have one before and It has a lots of advantage over ordinary frets...The only reason I dont like it is the lack of frets (only 21 frets :( ) But the rest is perfect and full of advantage ( only if you are used to it )such as :

Faster playing
Smoother note bending
Less stress on fingering hand
Cleaner, clearer notes
More responsive hand-tapping
Easier sweep arpeggios
Better trills and hammer chords
Quicker pull-offs
Opens new sounds and techniques, semi-tones, bending whole chords minor thirds, etc.

They are commonly used by the masters Yngwie Malmsteen, Ritchie Blackmore and John McLaughlin. When your fingers touch only strings and frets, new dimensions will open for you.

Measure the string height from the top of the metal fret for greater effiency, the feeler gauge can be purchased at Musicians Friend.

For the best set-up of your guitar, Ill just quote Yngwie for his set up coz he knows it better.........

(From Dragon's Fire, Volume 4, No. 2, March 1995) Yngwie says: "I use a hybrid set of Ernie Ball strings. The gauges on my standard Strats right now go 9, 12, 15, 24, 34, and 48. But this can vary somewhat, depending on which Strat I'm using (how deep the scallops are). On my Gibson, I use 9, 14, 16, 26, 36, and 48. I have all my Strats refretted with Dunlop 6000 frets. That's a big fret, but it works well with the scalloped neck and string height. Above the fret for the 12th position (high E) is about 4.5mm to 5mm. From the actual wood to the string is about 6 or 7 mm--it's really high, but I've become accustomed to it that way. I used to have it a lot lower, but I kept gradually moving it up because it sustains more."
