NOT stupid.Now I may be totally naïve - and I am - but I have a stupid question for y’all:
Why can’t you take a cheap @$$ bass, and have a luthier do a top notch fret job on it, and make it play like a $10,000 boutique bass?
(Told you it was stoopid)
The player is FAR more important than the instrument; and can make differences between inexpensive and expensive basses to be vanishingly small. So, first things first: Practice. The player makes the instrument great, not the other way around.
Still…the goal in performance is generally to forget about the instrument while playing, and concentrate on the bass part you are playing within the dynamics of the ensemble. Such concentration does require that there is minimal to no distraction by external factors, such as some issue with the instrument. Expensive or not, the instrument needs to be well setup, and have appropriate sounds for the performance readily accessible.
Inexpensive instruments CAN satisfy those requirements. But, it is also true that more expensive instruments may check the above boxes with less or no effort. Aspects, such as how stable / unstable is the neck with seasonal changes come into play. How well leveled are the frets? How well does the truss rod compensate for RH changes? How quiet are the electronics? Do the electronics achieve the range of tones needed? Is the instrument too heavy / light? Does the appearance bug you? Etc.
Further, it can be a waste of money commissioning an instrument, if you don’t yet know all those kinds of things; because you just don’t know what to ask for.
One of the most talented guitarists I ever worked with played a Squire.
Less expensive instruments can very definitely be modified; both setup and electronics - the latter especially if you are a bit handy with the soldering iron. So, there is that as well. But. You need to know what you are looking for and be prepared to learn by making mistakes.
Best of luck; enjoy the ride.
