yeah but it does sound like basses that i listen to on youtube or music
The basses you hear on youtube rarely sound like that is real life. They are run through graphic equalisers, compressors, a USB audio interface, and other fancy editing tools.
Even the bass you hear live (in a concert) doesn't sound like what the bass player is hearing. It is run through a DI box and front of house mixer, or a miked amp, or some fancy new ipad based mixer...
Meanwhile you have a very small amp and no fancy mixing gear. That said, you should be able to adjust your tone by playing with the bass tone control, the amp tone control and the balance between pickups (if you have more than one). Even changing the volume on the bass and amp can change the tone (bass on full, amp on 1; amp on full, bass up just slightly...)
Then there are strings,
flats and rounds sound different. Old and new sound different. Steel and nickel sound different...
and then there is the difference made by plucking the strings.
using 2 fingers, a pick, thumb slapping & popping with the fingers, using the flat of the finger, using a fingernail
Not to mention the difference a well setup bass makes. Look up a youtube video on bass setup (there are thousands) and work out if your strings may be too high, or your pickups too low...
Bass tone is a big topic and there is no one way to find what you want
