Sounds like the old joke:What are your amp settings? All of them. Your Rumble is obviously fine, but you are doing something wrong. You need to find out what that is and stop it.
Doctor, it only hurts when I do this.....
Well then, don't do that!

I think maybe you are using the wrong term to describe the sound. A distorted speaker will buzz or fuzz or fart, but not crack. Glass cracks. A high powered rifle shot cracks as the bullet breaks the sound barrier in a high pitched mini sonic boom. A board may crack and break under your weight especially if it is frozen. A lot of stuff cracks in the microwave.The crack sounds like a distorted speaker when I hit the low note once in a while.
Sounds like it could be your E string hitting the poles on your bridge pickup and causing the amp to clip. It would make sense as the E string has the lowest tension of all the strings (unless you have a B string) and it is happening in the lowest position where the string has the greatest length to vibrate.Hello all. I have a Rumble 500 combo. I recently added the Rumble 115 Cab. At times, I get a crack out of the 2x10 when I hit a low note. Sounds like it's clipping. Seems when I hit the low F or open E. Not sure if anyone with this combo had experienced the same thing?

So true! And good thinking @basslust. Strings too low and/or pickups too high are a recipe for sonic disaster. That could easily be the clack/crack sound.If you're playing in a drop tuning, this is even more likely to be the case.
I also thought that too until I played outside-you'll love that xtra booty.Oddly enough, that's how I got my Rumble 500c. My long time friend (and guitarist) bought it for me on the recommendation of a local music store employee he knows. Those guys aren't ALL bad! I was in need of a beefier amp than my puny home practice amp and a little 100-watt thing he owned. I've been thanking him for it ever since. (Well, I did pay for it really. I'd have likely gone Peavey or Carvin myself). But the perspective of a (good) music store guy who can play them all is really valuable. As much as I absolutely LOVE my Rumble, I'm not going to say it's the best amp ever built. If I had unlimited funds, or even made my living playing bass rather than just as a hobby, I might have another opinion. But throw in the price/benefit value equation and it may well be the best amps ever built. I've no doubt the 25 is similar.
(I keep trying to justify buying a 2x10 fender extension, but dammit I just haven't ever NEEDED it yet! And my band is LOUD.)
cool!Oh, but you do. You need to know you are Rumbler # 717! Nice rig. Rumble On!.
Right, that's why we played so loud. Had to drown out the hiss and hum.I've had my Rumble 350 head since 2012, and mine does not hiss at all. In fact it is the quietest bass amp I've ever owned. That doesn't help you, but it is not unusual for solid state amps to have low level operational noise to include some hiss. So that is normal. Like it or not. It's a good thing you young folks weren't around when everything was tube and ungrounded plugs! Talk about hiss and hum! LOUD too. You don't know what you're missing.![]()
Rumble On!

and the sound of the sirens of rapidly approaching policemen!Right, that's why we played so loud. Had to drown out the hiss and hum.
This reminded me of a hum issue I had about 20 years ago. I had a G&L SB2 that had never had a problem.and the sound of the sirens of rapidly approaching policemen!![]()
Solar Flares can be soooo pesky.I don't know if it is my ears, speakers actually breaking in, solar flare or what.
When I brought mine home from GC and played through it I was like meh, but after fiddling about with the knobs and buttons I was like wow. I'm actually using the Vintage button a lot now and I discovered that, for me, the OD takes very small tweaks to get the sound I like. I'm seriously considering a Fender Rumble amp head to push my Hartke stack. I'm a huge fan of my Hartke LH1000 (sounds fantastic), but it weighs a ton, and I really dig the Fender Rumble sound.Update: So my first impressions of the Rumble 210 cabinet were blah, however I've been playing through it a little each day and it is sounding better. I don't know if it is my ears, speakers actually breaking in, solar flare or what. This morning I played for 10 minutes at a low volume while people were sleeping. It sounded great. "My sound" was as I had expected/hoped.
Welcome Rumbler #714! Glad to have you with us. Rumble On!
I own the 115 and 410 cabs and over time (owned both for almost a year now) over time both cabs thru usage have really opened up. At first the sounded really stiff and sterile, now \\WOW// they really sound warm, responsive and handle everything I throw at them!Update: So my first impressions of the Rumble 210 cabinet were blah, however I've been playing through it a little each day and it is sounding better.

I did not realize there was a "break in" period for speakers....maybe its more of a gradual change thats easy to miss?I own the 115 and 410 cabs and over time (owned both for almost a year now) over time both cabs thru usage have really opened up.

Well, I've built a few cabinets in my time and have noticed slight differences from 1st play to many plays after. These Fender cabs in my experience with them, seem to open up and sound better over time..I did not realize there was a "break in" period for speakers....maybe its more of a gradual change thats easy to miss?
Yes there is. Specifically in the amount of excursion.Is there a difference between breaking in at a lower volume and "band" volume?
Go to someone elses house and play louder!I have a Rumble 200 combo and so far 80% of my playing has been at home at much lower volume.
Came across this article that explains it well:I did not realize there was a "break in" period for speakers....maybe its more of a gradual change thats easy to miss?
