Assuming the Forum has designed this SGF horn, who's going to build it?
Keep in mind that the design must be suitable to be executed on certain equipment.

I'll start working on a prototype in a week or two, if I can only find the time.

It literally choked the resonance of the guitar. So I learned the hard way.
There is more to building a PSG than meets the eye.

I think the holes will make a difference.
I have no scientific proof for that though.

Just ask Bobbe, he has a lot of information.

The table differs from yours in that the exposed amount is not a constant, but the numbers are optimized for least working time if you convert non-gauged rollers, because there is always an inclination angle across the tops of the rollers to be calculated which insures that 3, 4, or even 5 rollers can be left as they are, or cut to the same depth if made new.

Hope that helps anybody willing to do a conversion.

Other groove angles would require much more complex calculations.

Not very complex, really, but once it's done, it's done. You can enter any groove angle you want in my table (see my earlier post), but 60° is the standard, I think.

I sure do miss Carl! God bless him.

If a keyless guitar with no rollers and the guitars that use the same guage rollers work perfectly fine at the first fret without buzzing, why become so consumed with gauged rollers as the answer?

Why are so many Bud's and PP's found on recordings in the key of F using every possible combination of strings at the first fret, if buzzing was a problem for those players?

The string gauges determine the bars angle across them and this is all any guitar design needs to have a perfectly playable instrument at every fret. Proper bar control solves any buzzing problems at the first fret.

Having taught many seminars with Jeff, we would always ask the attending "If anyone had problems, playing or mechanical"? "Strings buzzing at the first fret because of soft bar pressure" always came up. We would sit down and play at the first fret without any problems and emphasis the importance of mastering the left hand.

The bar pressure needs to change per fret, however minimal, to maintain the proper sound and tuning. The first fret requires the most downward pressure. What's the problem with that? I know, the guaged roller argument is that it makes it easier to play, to which I say, "Watch Buddy Emmons play to see why we all should master a firm bar pressure as well as a softer bar pressure. Both need to be mastered. The bar is also used for creating dynamics all over the guitar. Those that want it to be easy and constant across the neck don't understand the musical dynamics that will eventually benefit them.

The plus about not having rollers or gauged rollers is that the player is not locked in to using the same guages on that guitar.

I am not a fan of guaged rollers. I love the freedom of changing guages at will without having to consider if the guage of the roller needs to also change with the string.

Its cool if you disagree. I play in C# all the time as well as F and have had no problems sliding from frets 0 to 1 or o to 2. I have alot of licks out of those positions with slides using the open position. I have played 12 strings and also had no problem.

Long before there were gauged rollers guys were sliding off and on from the open position and also playing songs behind singers in C# and F.
