I know this isn't any of my business, but be brave and try to fix the problem yourself.One day you'll need to make some adjustement on your bass and there will be not tech around to do it for you...besides the sooner you get to know your instrument, the better.
Now, I'm gonna try to help out giving some ideas on how to set your bass but if I'm wrong or I'm missing something, please people correct me!
There are 4 basic things you can adjust on your bass and that sooner or later you'll need to do:
adjust the neck relief
adjust the strings height
setting the intonation
setting the pickups height
Let's skip the neck relief for now since it's a little more complicated and you may want to wait to work on that.It sounds like you just started playing bass, but if I sound too pedantic or say things that you know already, please excuse me.
Rising or lowering the action (strings height) is very simple and can be done adjusting the saddle hight at the bridge with the hex screws. You can start with your lower string, checking the open string and all the frets up and down making sure you don't getting any buzz. Once you found the sound (but also the feel!) that you're looking for you can move on to the next strings. You will notice that shape of your fretboard has a slight arc to it. this arc is called fretboard radius, and the height of the saddles (do not measure the top of the string, but the saddles, since strings have different gauges) should pretty much match the curvature of the fretboard.
To do that you can use a radius gauge or eyeball it. The point is that it's gotta feel balanced and natural to play.
Once you've found the right strings height you can move on to setting the intonation.To do this you will have to shorten or lengthen the strings by moving the saddles forward or backward with the screws at the back of the bridge. This is very easy to do with the help of a tuner: tune all your open strings to the correct pitch.Starting again with your lower string fret it at the 12th fret making sure that you're pressing it straight down and not bending it. Check your tuner again and you may find out that your string is flat (b) or sharp (#). If it's flat you'll have to shorten the string moving the saddle forward, if it's sharp you'll have to shorten the string moving the saddle backward.Do the same with your other string, checking that the open strings are still in tune. It's impossible to get all the frets in perfect tune, so you'll have to compromise (if you wanna learn more about this check just intonation and equal temperament, here
http://www.phy.mtu.edu/~suits/scales.html for example).
Last but not least you can set your pickup(s) height, this can of course be done tightening or loosening the screws that are at the side of the pickup. Too far from the strings is gonna lower the output of your bass, to close is gonna kill your sustain (due to the magnetism or the pickups), find a compromise. Also remember that the pickup can be set at an angle, so to have a more balanced output from the different strings.
Remember that different strings gauges may work differently with your setup or that simply changing the strings may change the height of the saddles etc. so you'll need to check and adjust it again,
None of this stuff is gonna do any harm to your bass, so experiment and find the setup that works for you; and of course keep practicing and you'll get a more confident and softer touch. And have fun!
I hope this was helpful.
p.s.: small adjustments!
