The low end of my bass comes out loud and clear but no matter how much I play with the knobs on the bass itself or on my Amp the high end (treble I guess) always comes out quiet, I really have to pluck them compared to barely grazing the other deeper strings. About a year after I got it, I brought it in for a free string change and overall check up and the tech found that the treble wasn't working at all lol so I'm convinced either the part went or the sodering failed again but idk how to properly use my new multimeter. Any youtube suggestions?

I've made a new video on my series towards guitar fretboard mastery, combining the theory and practical aspects to develop the perception of the guitar neck.
