I recently acquired a Fender rumble 25 bass amp and when i turn the volume up past 5 with the bass/mid/treble turned to the middle, the amp will start to crack and vibrate with distortion resulting in a terrible sound when playing the E-string on the 10-14 frets. This also happens when i turn the bass/mid all the way to +15 and the treble to -15 with the volume at around 3, playing the same frets.

Is this normal? Or does the amp have something wrong with it? If it does, what can i do to fix it?

I run a Dean Playmate with a Prolink Bass Monster cable.

it's just a starter amp... check the screws in it and make sure they're tight... if so, check to see what is physically rattling.... then duct tape it

I have that amp, it does the same. It's meant as a practice amp so don't push it.

Ok, good to know. Have you ever used a bass equalizer pedal on it?

All screws are tight.

I use an EQ with it, gets a cleaner tone. Not much louder though.

Boss GE-7, meant for guitar but I like it better than the bass version.

When you hook that up to your rumble 25, do you use the effects loop? If so how do you connect it? I basically have no idea how to use the effects loop.

I tried the loop and putting it in front of the amp, didn't make much of a difference except that in front of the amp uses 1 less patch chord.
#11
So to use the effects loop you use a cord going from the pedal to the preamp in, then from the pedal a cord going to the guitar and thats it?

Plug the send jack into the input of the pedal and plug the output of the pedal into the return jack.

Yea the Rumble series really does have that "rumble" from it being too weak to carry a deep signal. My Rumble 15 is notorious for that.

A effects loop works like this.

Bass>amp>effects send>pedal input>pedal ouput> Effects return.

you'll need three cables to run this setup.

We have a rumble 60 in the basement and while it can keep up with a Peavey Classic 30, the tone noticeably alters, and sounds terrible when cranked :/

Yep, i got it for a steal though so its not as bad as it could be, i thought it had some good tone but the loudness of the amp is just horrible. At full volume ( but low enough so theres no distortion) with the bass EQ cranked its about normal practice level when your by yourself. Anything higher it starts to crap out.

Not a good buy at around $200.

You need an amp with more wattage. End of story

Yep, that about sums it up. When i save up ill shoot for a 100 watt.
