Scale length is the distance from the nut to the bridge saddle, the part of the string that actually vibrates. It changes how a bass feels, how it sounds and how big it is. Here's how to choose between short, medium and long scale.
The three common scale lengths
- Short scale (30"): the smallest and easiest to play. Frets are closer together, string tension is lower, and the tone is warm and thumpy.
- Medium scale (32"): a middle ground. A little more compact than a standard bass, but with more punch and clarity than a short scale.
- Long or standard scale (34"): the most common bass scale. Tighter string tension and the clearest, most defined low end.
How scale length changes the feel
A shorter scale means less distance between frets, so big stretches are easier. That's why short and medium scales are popular with players who have smaller hands, guitarists who double on bass, and anyone with wrist or shoulder strain. The bass is also shorter overall, so it balances closer to your body.
A shorter scale also lowers string tension for the same tuning. Strings feel looser and bend more easily. Some players love that, and others prefer the firmer feel of a 34".
How scale length changes the sound
Lower tension gives a rounder, warmer, more "thumpy" tone with less high-end sparkle. That's the vintage short-scale sound many players chase. A 34" scale has more tension, which gives a tighter, more focused low end and more definition, especially on a low B string.
That last point matters for 5-string players. A low B needs tension to sound clear, so a 34" scale is the safe choice. A 32" medium scale is a popular compromise for 5-strings if you want a more compact bass, as on our Thunderhorse V in Black Sands.
Which one should you choose?
- Choose 30" short scale for comfort, a vintage thump, home recording, and players coming from guitar.
- Choose 32" medium scale if a 34" feels like a stretch but you still want punch and a usable low B.
- Choose 34" long scale for the classic feel, the tightest low end, and the widest choice of strings.
Common questions
Do short-scale basses need special strings? Yes. Buy strings labeled short or medium scale so the wrapped part of the string fits your bass.
Will a short scale sound "less like a bass"? No. It sounds warmer and rounder, not thinner. Plenty of famous records were cut on short-scale basses.
Is a shorter scale lighter? Usually a little, because the neck is shorter. Body wood matters more. Basswood is our lightest body option.
Build it your way
Every McGrath can be built in 30", 32" or 34" scale, in 4 or 5 strings, and fretted or fretless. Choose your scale in the Bass Builder, or ask us if you're not sure which will suit your hands.
