Is this correct?

You should be able to answer that question in about 2 seconds with 2 seconds of thought...

nut to 12th fret - 34" scale, 17"
nut to 12th fret - 35" scale, 17-1/2"

so the answer is no.

 

No, the distance between the frets is fixed for each scale. I wouldn't sweat the extra 1" though. I used to switch between a short scale 32" and long scale "34 and it only takes a couple of minutes to get used to the different scale lengths.

I might worry a bit about the extra length plus the extra frets. But once you are really comfortable with each bass, the switch shouldn't be bad.

 

No, the distance between the frets is calculated from the scale length. Although not that much different, if you put the frets the same distance apart on a short scale as you did a regular scale, you would not be able to play more than the first note on each string in tune, if that. Quite possibly, only the open strings would be in tune.

 

Hammy has that way about him, huh? I think it's his most endearing trait.

 

Regarding the extra frets - let's supose on your 22 fret bass we removed all of the frets above the 12th fret. Or better yet, we just remove the 21st and 22nd frets. Would that affect the spacing of any of the remaining frets? Your bass doesn't know whether the frets are there or not. Adding two more to a 22 fret bass doesn't change anything other than you have two more frets. It's all about string length, gauge and tension. Basic physics and geometry.

 

No, I think we understand. But I think you have it the wrong way. One of my short scale basses had more frets and I found it felt *longer* than the long scale basses. I think more frets on a longer scale will actually feel a bit more "different" than two basses with a different scale but the same number of frets.

I think we all get what you're saying. It seems to me as though you're looking to get an answer similar to "The distance between frets 1-2 on the 34" is nearly identical to the distance between the nut and fret 1 on the 35". I could be way off.

If that's the type of answer you are looking for, it's a moot point as you'd have to transpose up a half step to maintain the feel (or downtune).

 

(Bold mine)

No. All it means is the fingerboard is extended towards the bridge. The 20th fret (or whichever you choose) will be the same distance from the nut no matter how many frets are after it, assuming the scale length is the same.

 

When was the last time you saw a 24 fret bass where the frets went from nut to bridge? The 12th fret is ALWAYS 1/2 of the scale length (adjust for intonation....). If you look at a 22 fret 34" instrument and a 24 fret 34" instrument, all the frets should (ie will) line up and the fingerboard of the 24 fret bass would be longer.

 

No, you're thinking of it wrong. 34 inches means 34 inches from nut to saddles (neglecting intonation distance). The 12th fret on a 22 fret bass and a 24 fret bass (assuming they are both the same scale, whether it be 34 or 35 or any other) will be in the SAME SPOT in relation to the nut and the saddles. The amount of frets does not change where the notes happen on the string, the scale length does. The more frets just mean you have access to more notes than you would with a bass with less. When you add more frets, but keep the scale length the same, the fingerboard gets longer, but the nut and bridge stay the same in relation to each other. Make sense?

 

he said it nicer than i did

 

I thought I ought to be pretty clear, just to be sure.

 

To find the position of the frets on a fingerboard, you take the length of the scale 34 inches and you divide it by 17.820
34" divided by 17.820= 1.907 which is the position of the 1st fret.
you take 34"-1.907"= 32.093
you take 32.093" divided by 17.820"= 1.800 which is the position of the 2nd fret and you just keep going to as many frets as you want. But the distance between the nut and the saddle will always be similar within the same scale and the 12th fret is the beginning of the second octave or the mid point without the compensation of the strings.
The magic formula some books say is you take the scale and divide it by 18, others say you divide it by 17.848, and again others say that you divide it by 17.820.
So the best thing to do is to buy a ruler that the scale is already figured on it and accurate.
