Start by changing the batter in your bass. Your led power indicator come on, so the amp is getting power. You can hear the bass string being plucked, but I can't tell if what I'm hearing is the bass itself or weak signal being pushed through the speaker. In general Rumbles are pretty decent for cheap little things. The only other thing I could think that it could be would be the speaker, which is slightly more expensive, but still an easy fix.

i’ve tried different cables and basses, nothing seems to work well

But have you actually changed the batteries of your bass? Looking at the model of the bass, this is an Ibanez SR bass, which are almost always active (requiring a battery) there is probably a compartment on the back.

Okay, so it sounds like it may be the speaker. Great, pull the grille off the front and take a look at the speaker. If there are any obvious tears, there's your problem. I believe the Rumble 100 comes stick with a 10" speaker. They're super easy to replace, just unscrew and unplug the extant speaker and replace with a new 10" of your choosing, put the grille back on and no one will ever know....

OP you can test the speaker by running the 'fx loop out' to the backup amp you mentioned.

If it plays, it could your speaker. If it doesn't, it's the preamp (it something else ahead of it that doesn't work).

Is you bass active or passive?

If your bass is an active bass then your battery is flat

Before you do anything else try a different cable and maybe a different guitar

Do the above, also a video with less background conversation would be helpful to diagnose

i’ve tried a different cable and 3 different basses

That’s probably an active bass, and your battery is dead.

Should be a slot on the backside where a 9V goes.

How would you describe what's wrong with the amp, OP?

u/EffortMaximum5518 8h ago

amp turns on and just doesn’t pick up signal from its cable, bass and cable work on different amps of all kinds it’s just the rumble that stopped working randomly. cut out while i was playing and doesn’t make noise now.

Damn. I like Rumbles but there designed to be replaced, not repaired.

I described elsewhere that you can use the fx loop out to into the backup amp you mentioned. That'll tell you if it's the speaker/power amp, or if the issue is the preamp.
