Hello from Finland
First - welcome to LTG
Second - things to check : try your bass into other amp - try your amp with another bass. This will tell you where the problem is - bass or amp.
Third - tell us more - who are you - whereare you - what you play - what gear, style etc
Hello, Nuuska! I'm April H., and I'm 60 years old. I've been playing on and off, for 45 years. I live about 50 miles NW of Chicago, near the Illinois/Wisconsin state line. Where the coyotes howl and the hoot owls hoot.
I have 4 Ampeg amps, a small combo, a medium combo, a large combo, and the rig I've used most in the past, an early '70's Ampeg V4B that needs to be worked on so I can use it again. I also have a Boss Katana amp. I haven't used pedals much, but I have three now: An ancient Sovtek Big Muff(which only sounds good with the tube amp), and I recently bought a Darkglass Microtubes pre-amp/pedal, and a Joyo Ultimate Drive. None of which I know how to use except the Sovtek. I'm not really a pedal gal, but I decided to experiment.
Other gear I have is a Sterling Sub bass, which IS active, a short scale Squire Jaguar bass that is doomed because the truss rod is frozen, but has a really nice set of pickups someone added(Bass Lines in the neck position, and a Seymour Duncan in the bridge), a '67 SG, a Hello Kitty baby Squire guitar, 1 old Suzuki archtop acoustic, an old Harmony Tenor guitar, an Ibanez wood bodied resonator guitar, 1 regular Epiphone acoustic, and a PRS SE Baritone guitar, and a student sized cello. Most of this stuff is used, and bought for not a lot of money. The SG was given to me, but the headstock was broken, of course.
When I was a teen, I listened to punk rock, and was involved in the Chicago punk rock scene. Some great bands came out of there. I played in an all girl band, and we moved to Hollywood to strike it rich. Of course, that didn't happen. I was really into "grunge" when it came out...and was sad when it went away. I'd have to say my favorite band right now is the Foo Fighters. I'm into loud, aggressive music, I guess.
Hope this wasn't too long or more info than you needed LOL. P.S. I don't know if you're into Formula One racing, Nuuska, but my favorite driver is Kimi Raikkonen.
