That's because "best" is subjective. A lot of folks love the sound of a Stingray, and will say they're the best basses they've ever played. I've never really warmed up to them though. A lot of it just comes down to personal taste.Wanting to stay in the under $300 range, what short scales are good? I see the Fender Mini Precisions, Fender Squire Sonic Broncos, Jacksons, Ibanez, Music Man... reviews are all over the place on which is "best".
It's tough to know what makes an instrument the best for you when you're just starting out. I would suggest narrowing it down to a short list of options that you like the look of - I know it sounds superficial, but it is important to have an instrument that you want to pick up and play. Then from that short list, look on Reverb and see what they sell for used. If they sell for not a lot less than new, that's a good sign that you'll be able to sell it later on if you want to replace it with something else.
You also might want to think about what sort of bass sound you like. Again, this is harder as a beginner, but are there recorded bass tracks that you hear and think, "yeah, that's what I want to sound like"? If so, drop a link and we can make our best guess as to which sort of pickups will get you closest. A P bass, jazz bass, or Stingray style bass all have different tonal characteristics, and if you want the sound of a Stingray you'll find yourself disappointed with a P bass. (Keep in mind that your amplifier will also affect a lot of your tone, what sort of amp do you have or plan to get?)
With any instrument in the low budget range (and sometimes even at higher price points), there is always a chance that there is some sort of quality issue, so when you do get your instrument a few things that you should look out for include:
- Are the fret ends along the edge of the neck sharp? Sometimes they will "sprout" out of the wood. This isn't too hard for a luthier to fix, but it will add to the total cost.
- Are the frets well seated in the fret board, or are some of them starting to pop up?
- Is the neck tight in the neck pocket? Is it mounted straight on?
- Do the strings look like they're well centered on the neck, or do you notice that there is more room on one side of the fretboard? This will be most obvious at the heel of the neck, where it connects with the body.
- Is the neck warped/twisted? I'm not talking about a little bit of curvature or bow to the neck, that is adjustable to some extent with the truss rod. A twist in the neck is a much bigger problem.
- Are there any scuffs/dents/dings in the wood that will bother you?
- How does it feel to turn the knobs? Do they feel loose, or do they stay where you set them? Some crackling while turning isn't necessarily a problem, but if it doesn't go away after turning the knob up and down several times, it may be a bad potentiometer.
