I have only seen this recently, from the guys at Andertons in the UK, Rob Chapman had a low buck build on contest between him a the other guy that calls himself the captain, anyway that was the first I had heard of it and while interesting I am a very tactile player and my finger usually goes all the way to the wood while fretting. Don't know if I could play a scalloped board.. never held or tried it though...
Scalloped necks take some getting used to , without getting the cheese cutter effect. they require only a feather light touch compared to a regular neck , and are more-so beneficial for speed metal or very fast playing .
most scalloped guitars you see are done at home by their owners with a rasp / file .
but it has to be done carefully .
very very few manufacturers include this process . i believe the ibanez jem , has the first 4 frets scallopped , but very slightly
Had one. LOVED IT! If the guitar already has low action it's like playing on air. Most people never realize they're pressing down on the fretboard of a guitar to hard. Playing on a scalloped fret board on a well setup guitar is a great way to find out.
Fender makes scalloped guitar necks.
Personally I think most manufactured scalloped necks are cut in to deeply. It doesn't take much to remover the necessary wood to make it work. Possibly done for show? Because it looks cool I guess.
If you do plan on making one for yourself remember the frets need a strong base to sit in. And don't go as deep as you see in the store bought necks. All your doing is removing the 'landing' wood for your fingers. Remover 1/16 and start from there.
I had no trouble at all playing any song I knew. Very comfortable to play. However string bending did take a bit of getting used to.
and for something completely different, but on topinc,
Richie Blackmore - guitarist for 70's Rock band Deep Purple and Rainbow played a Strat with a neck that He scalloped with a file.
Benefits are fretting with less pressure and bending sharp with a little pressure. If you use tall frets like jumbo or super jumbo, you can get a similar result.
