Re: Why are the frets "scalloped?"

i think its meant to make playing faster easier or something along those lines , dont seem to do much if you ask me and all the satch guitars dont have it and he seems to play ok.

They are supposed to help you not get "Choked up" when you bend notes in the upper register.

Re: Why are the frets "scalloped?"

On Jems, I thought the reasoning for scalloping the high frets was to increase sustain. With the old neck joint, there isn't a lot of neck wood under the fretboard on those last frets, so you want the cleanest possible contact between the strings and frets.

With the AANJ, the neck extends all the way to the last fret so it's not necessary to scallop for tonal reasons. (But they do it anyway for historical reasons?)

See the full explanation near the bottom of this page:

http://jemsite.com/axes/htm_features/spec.htm

You can see the difference between original and AANJ necks here:



That's the reason Jem fretboards are scalloped. Usually, people (like Malmsteen and Blackmore) use scalloped fretboard because they like the feel of having no wood under their fingers. I've never played a fully scalloped fretboard but I imagine intonation must be a pain.

Interesting, I didn't know that. The explanation still doesn't make sense to me, however... why does scalloping get you back the sustain you lost by having less wood mass behind those frets? Does that explain why scalloping on an AANJ neck doesn't add further to its sustain?

I'm guessing the reasoning is that you can press the string down harder, giving you better contact between the string and the fret. I don't know if this actually makes a difference--I hear a lot of pseudo-science get thrown around when it comes to guitar construction.

Re: Why are the frets "scalloped?"

as far as i know those scallops were meant to increase sustain and make the playing easier in the upper registers. And it IS easy to play with a scalloped fretboard. you don't need to apply so much of a pressure to get the sound clean...

Re: Why are the frets "scalloped?"

Sustain and bending is much better. Intonation is not a problem if you play lightly. a little wierd getting used to no wood under your fingers, but I'm a big fan of scalloped necks.

Re: Why are the frets "scalloped?"

The scallops on the original neck joint were intended to give more volume and pure tone from those last four frets, to help balance them out with the other 20 frets.
The nature of the fretboard overhang (as shown in the photo above) means less wood-to-wood contact from neck to body, and so some string energy is lost.
Add to this the loss that happens from the flesh of the finger tips drawing off some as they contact the fretboard wood.
The scalloping reduces this by keeping much more of the string's vibrational energy in the string.

Because of easier bending.

Re: Why are the frets "scalloped?"

I can second the volume and sustain argument- there's a noticeable change in "impact" on the last few notes on my UV7PWH (old style neck joint) that's not present in my 7620 (new style neck joint). I'd try scalloping it, but, well, it's such a gorgeous inlay...

Re: Why are the frets "scalloped?"

Drew... If you go very carefully, you can scallop about 1/32" and those inlays shouldn't vanish... I queried LGM as to the thickness of the UV777BK inlays, and he told me they were only about .040" thick...
With that info in-hand, I scalloped the top four of my UV777BK... And thankfully, the inlays are in fine shape, just ... scalloped.
=]
I did this on the BK for that extra bit of grip (same as on my RG7-620GN)... And I did my '91 UV7BK for all of the above reasons.
=]

Pics are here: there's a decently close shot of the UV777BK - although slightly out of date, it's pretty much the same.

Click the pic of the UV for a closer look...

Re: Why are the frets "scalloped?"

I never used to like the feel or sound of the scalloped frets on my Jem (just my opinion, I know lots of you love it) - to my ears the scalloped frets sounded "hollower" than non-scalloped - it definitely affects the tone anyway. I can understand it being a bit easier to bend strings, etc, although if you push down too hard it can affect intonation a bit - I'm happy that none of my 7's have them scalloped anyway, since thats all I play these days (different strokes, etc, lol).

frets are scalloped because it's so difficult to properly 'au gratin' them.
