Why 34" scale?

How did it come to pass basses have a 34" scale?? Did Leo just pick this number? I'm sure there's an answer probably related to stand up basses.
I did a Google search and searched here, but I can't find the origins of scale length.
Just curious...
Cheers
 
I don't believe it had anything to do with double bass scale length, which is generally between 41" and 43".....
I could be wrong.

Oh, but there is an obvious numerical relation: take the digits 43, reverse them, and you get 34! :D

I have no idea what the real reason may be. I don't suppose that it would have been impossible to use 43 for some of us anyway. That is only 9 inches more than what we have. More folks can reach fret one on a 34 though, plus it is easier to swing around on stage so there are good reasons to be shorter than a DB. I just don't know if there are any specific reasons to pick 34.

As I recall, Leo Fender didn't design an electric bass just so it could be amplified. The other factor was portability: no reason to stick with 40+ inches of scale length with an electric instrument... not when one goal is to allow players to carry it easily in their car (or a taxi).

My hunch is that 34" was simply an educated guess on his part. Not that 34" is the "best" scale length for electric (longer and shorter scales can work just fine, after all), but after 60 years the spec has certainly proven itself well enough.
 
I'm pretty sure that it was decided that 34" was an appropriate length for low E string to intonate & function well. Any longer and the instrument becomes cumbersome to play, any shorter & the E string starts sucking.

Hence the 35" scale length if you add a low B, and the difficulty in finding a 34" 5-string with a decent B......
 
There is no difficulty in finding a 34" bass with a good B string, IME, IMO.
I've had plenty, and have 5 or 6 right now.

Ditto.

String intonation and performance will of course depend on both scale and gauge. Electric bass strings have been designed for 34" scale length (unless otherwise specified), rather than the other way 'round. I'm not sure that electric bass strings were even available back when Leo created his P-bass. ;)
 
Agreed - I've owned a few 34" basses with good B strings, and currently own 3...

Fair. I have two.

Point being, you can't assume that a 34" B is going to be worth a damn. I once checked out a whole showroom full of Warwicks and couldn't find one where I thought the B sounded good.. And this was with string changes & setups. Nothing against Warwick, hell, maybe the shop was just putting the wrong string gauge on em.

the problem here is that most of W. basses do sound like s*****

;)
 
According to Jim Roberts book, "How the Fender Bass Changed the World", it was a combination of information from a physics book owned by Leo's secretary and/or trial and error - George Fullerton said they tried 30" - 32" and possibly 36", but chose 34".

Nope. That very small percentage difference between a 34 and 35 inch scale is pretty trivial regarding B string tone. String design and neck stiffness have a much larger impact. All of my 5 strings are 34" scale. The fattest, most amazing E string I've experienced (by amazing, I mean big and huge sounding) is on my 30" Rob Allen Mouse, most likely due to the piezo pickup and the buffering preamp).

Everything that I've read concerning the development of the early Fender P bass scale describes Leo and his crew just trying different scale lengths until they found one that felt and sounded OK and worked with the design. Relatively 'unscientific'.
 
This is total speculation on my part, but here goes: A typical DB scale is ~ 43". A typical guitar (Can we use that word on TB? I usually call them "six string short scale piccolo basses.) is ~ 25" scale, right. The average between the two is 34". This give portability relative to a DB and allows the guitar (pardon me, again) player to adapt to the instrument.
 
I read somewhere that Fender actually built some prototypes for the scale length...

I don't know what other scale lengths he tried, but, 34" seemed to work for him with the materials and construction methods of the time.

I wouldn't have chosen 34" myself....I would've chosen a scale between 32" and 34"...maybe 32.8, or 33". A little bit more comfy for my arms.

I have a 32" scale ABG and it's so confortable to play.
