I don't like my Rumble 100, help me find a solution

I was really close to replacing the speaker on mine, the reviews are favorable; but ultimately decided not to roll the dice on the mod and just get another amp. I ended up with a Markbass 121p and its head and shoulders above. (I still like the rumble for low level jams, but it has limitations.)

I was also really close to a GK MB amp, 112 or 210 (though these have really gone up in price.) Ampeg Rocketbass would be my recommendation if you want to stay in a similar budget.

My experience is similar. The Rumble 100 that I had was not clear to my ear, no matter what I tried. I sold it and purchased Markbass Little Mark 250 Blackline and a Markbass New York 121 cab. Def an upgrade for me. Best of luck with your decision.
 
New EQ settings
Don't boost frequencies to try and fix it. You should cut the bass and low mid to clean up the mud.

Speaker replacement
This is a waste of money on a budget amp in my opinion. You are better off selling the Rumble and upgrading if you can't get it to work for you.

Downgrade to the rumble 40

Also a waste of money. You'd be better off going for the 200 or 500 if you want to gig, the 100 won't cut it anyway.

Get a new amp

The Rumble 100 might just not be for you, that's totally fine. I would go to a shop and try out a bunch of different amps until you find something that gives you the tone you like.
If you have a tight budget, try it out in the shop and then find one second hand on Reverb or Facebook. Make sure to test before buying.

As far as recommendations, I would say you need at least 350w @ 8ohms into a 2x10. Be it a combo or seperate head and cab. Stick to name brands and you will be fine.
 
I own a Rumble 100 which I use for low volume level rehearsal. I don't think it exactly sucks, but I have very low expectations for how an amp in that price range is supposed to sound and for me it is good enough. If yours sounds like you are suggesting it sounds, in my estimation it is either a problem with the amp or a problem with your ability to set the EQ. My guess is that it is the latter.

If this is for playing at home, just ok should be good enough. I mean, its not like you are going to be gigging a Rumble 100 anywhere. Yes, I am fully aware that someone will jump in here and tell me how they played MSG with a Rumble 100 and it was more than enough to hear over the drummer without monitor support.
+1 When I bought my Rumble 100 about a year and a half ago it took some time with the EQ settings to find what I liked. Mostly just needed to dial back the bass and low mids, it was a little bottom heavy and lacking clarity. Once I got the EQ figured out I enjoyed the amp and continue using it all the time for rehearsal and small venue gigs.
 
I have a rumble 100 and I can tell you that the vintage button definitely stays on. I consider this to be a very good practice amp and nothing more. So playing with a band, I doubt it will sound good.

Also, if you are used to a combo with a 15' speaker, a 12' isn't going to come close. Very big difference between 1 15 and 1 12. I used to gig with an ampeg B2 with a 15. I just wouldn't do that with a Rumble 100.

I use one for a rehearsal amp. Hi pass in the fx loop, and raising it off the floor help(especially on a wood stage or drum riser). I upgraded to the Basslite, it gave it a little more hi mid mids and high mids, but won't fix a boomy sound. Bass around 10 o'clock, lo mid and hi mid 1 or 2, treble 2 or so, occasionally click on the bright, Wick Corvette w/Daddario nickels. An EBO with flats probably would boom anyway.

Change the speakers to Neos, it should increse the clairity of the tone IMO.

12 inch- Eminence DeltaLite II 2512
15 inch - Eminence DeltaLite II 2515

I found the non-Neo magnet speakers a bit muddy; been using (over 3 yeas giging) two Rumble 1x12 stand alone cabs (out of production) with DeltaLite II 2512s and they are great. I prefer the sound of 12 inch speakers over 15s.
 
Yeah, I had a Rumble 500 head and have used a Rumble 40 in a practice space.

I used the head with a Carvin BRX 410 or a vertical stacked Avatar 210. I always felt the 500 was a little mushy compared to my Little Mark III, which is still my main head. I sold the Rumble and got a Peavey MiniMax 500 head to use with my cabs and was much happier.

With the Rumble 40 I set the bass all the way down, maybe on one. Then the mids were left around even or maybe cut 9:00, and the treble all the way up or around 3:30. So maybe that would be bass at 7:00, mids 9:00, treble at 3:30. DI sounded ok, usable but not great. I brought my Sansamp BDDI next practice and the whole thing sounded much better, and went DI to board from the BDDI.

Go look at other used amps at music stores if you can. I can recommend used GK, Markbass, or Peavey, or TC Electronic as some possible inexpensive ones or used GenzBenz can sometime be had for a deal. Check Guitar Center's used section or Reverb or Ebay as well as TB Classifieds and do a little research.

I have owned a Rumble 15 for pretty much my whole time playing bass. It sounded pretty poopie so I wanted a replacement. I heard people praising the other Rumble amps in the line, and I thought it would be a great decision for a great practice/gigging amp that's light, loud, and good-sounding.

What I have is that while it may be light and loud, it most definitely is not good sounding; it sounds like it is under a blanket and is super muddy, while sounding super boxy in the mids, and flat in the treble. I have tried all of the settings one could imagine (yes, I know that flat is around 10/2/2/10 o'clock for the knobs. It also didn't really help.), even with the bright on, it still sounds muddy. When I boost the treble to unreal amounts with the bright on, the treble is harsh and not zingy how I would want AND THE MUD IS STILL THERE!!!!!

I honestly am desperate for help, as all other amps in my price range don't seem to fit my needs (Ampeg Rocket, orange crush, etc.), so here are some solutions I have come up with.

A. New EQ settings (I highly doubt this)
B. Speaker replacement (I heard the Eminence Basslite S2012 neo speaker really improved the sound, but I'm still skeptical if it will give me the sound I want)
C. Downgrade to the rumble 40 (Heard it sound clearer, but I want to be able to gig)
D. Get a new amp (Would like recommendations.)

Any other suggestions would be greatly appreciated, Thank you!







Maybe, it's just that the Rumble series combo's voicing just doesn't suit what "your ears" want to hear.....and no amount of knob tweaking, driver replacing, or up or down grading to a different model Rumble will change what your looking to hear.

If you have any brick and mortar music stores anywhere reasonably close, go, take your own bass, play through everything, listen for what YOU like.
Don't consider what the name brand is or the cosmetics, it's all about your ears!

If there are no music stores near, go to YouTube, research and listen to all the amp/cab/combos reviews you can, go to the net, research amps that might interest you, go to where live bands are playing in your area, watch and listen to what their bassist is using, do more of what you've already done, come to T.B. and ask questions.

After your research, make a list of several amps/cabs/combos that you believe will be what your looking for.

If going new, look into Sweetwater, Musicians Friend, Guitar Center, ect. websites.

I'd recommend thinking used but not abused and making your dollars go further by watching for equipment from your list from the T.B. Classifieds.

Keep in mind that any non-reversible modifications will void any remaining warranties. Otherwise, you might try adding some acoustic fill material to the Rumble 15, if you still have it, or some acoustic liner material to a few interior sides of the Rumble 100. It has tightened up the sound and eliminated the boxiness for several members of the TalkBass Fender Rumble Club. The smaller models 15, 25, 40 & 100 don't come with any, but the 200, 500 & 800 come with a few lined sides.​

Did you ever think of asking those in the Rumble Club?


The Soul man is right. There are lots of knowledgeable and helpful people there, whether desperate or not.

You have been auditioning the Rumble for quite a while and don't like it , time to move to a different brand . Like many have said take your bass to a music store and try as many as you can to get a tone close to what you want to hear . Your ears are going to be the judge , that's the best way to pick .

I used a Rumble 500 combo for years on gigs.
I liked it.
However, it does have an older sound, and I also started to favour the more modern, clearer sound.
I didn't have the funds to go super high end, so I got a Markbass rig.
It offers more clarity, punch and cuts through more in the band mix.
Lightweight too.

It’s perfectly ok to not like the Rumble. The first step to recovery is admitting it’s time to move on.

There’s some good suggestions above
I don’t do a lot of Jazz stuff, but I moved on to Ampeg about 8 years ago. I’ll never buy another Fender amp

Rumble 100 - Loved the sound. For a week. Then I grew tired of it. No matter what bass I played through it they all sounded the same. Same baked-in boxy thick tone.

I preferred the tone of the Rumble 40 for home practice.

I ended up moving to an Ampeg Rocket RB112 which to my ears sounds much better More balanced, less colored. I use 99% as a home practice amp but am still loving my tone through it over a year later.
 
Place here. Lift with legs, not back. Or have a friend help you....
