Just got a Rumble 200 - Low B muddy

I had a Rumble 500 head for a while and found that those amps have a baked-in low end boost. The tuning of the 15 in the 200's cab probably doesn't help. It makes the amps sound great at bedroom volumes, like engaging the "loudness" button on a stereo receiver, but they can become obese sounding as you dial them up.

If you haven't gotten rid of it yet, try rolling the low mid control down...I ended up at full CCW...and roll off the bass to taste. I even engaged the contour to scoop out more low mids.

Good luck.

I totally understand if I'm coming across a bit snobbish with this. I am generally not in the market for combos and think many brands put lesser components into them compared to heads & cabs, even nearly identical ones. I don't think MB does that but there are a lot of threads on here where everyone is severely polarized about MB, extreme love or extreme hate and in between is no man's land. Without doing science about it, seems many of the bad experiences are with combos. I own two combo amps, both Peavey Combo 300s from the 80s. My small at home rig is a PF50-T into a TC RS212. So that's one part I'm generally not fond of, but more important for you I apologize I don't have much in the way of which combos to recommend.

I think MB are more proud of their gear than they ought to be. I don't love all the colour schemes, in the car audio world generally yellow cone speakers used to be an indication that looks were more important than sound. Some of the heads in particular have what looks like cheap plastic faces that would easily crack or discolour in the sunlight. So that's part of it also.

I think the sound of most MB heads is about the same flat, the vintage sound they're able to achieve is good yes, but for the money you spend to sound like old tube gear you could buy old tube gear in good condition. For the money you spend to get a very crisp clean modern sound, you can do it better for less (Carvin would have been my counter-example there), or 'better' now for about the same (Mesa, Quilter, Darkglass, Aguilar) depending on your version of better and your cab selection. Like you I also like my mids, and especially the mid-high range where the honk is, but you need a microscope to dial it back (assuming MB head & cab, or combo) enough to tame it without losing what you do want. MB head into a generally more 'clean' cab (in my case Carvin BRX10.4 with the tweeter off) does let a much nicer sound shine through. The reason I do use the MB primarily with my 5 (Carvin LB75 with Roto 66) because of the clarity I get out of the B string; the upper mid & high EQ knobs are actually what really gets it there.

There is something I can't quite put my finger on about MB that, while I'm a fan of Ampeg I hate their SS stuff; while I love classic 70s-90s Peavey I tried but couldn't like the Mini Max; Bassman yes, Rumble no. It's not fair to compare classic Acoustic to the current 'Guitar Center owned Acoustic brand', but that's another one. Maybe by giving these examples you can understand where I'm coming from, MB straddles the line for me between what I like and don't like.

Generally I play covers. Could be any kind of rock from 60s-early 00s, my ideal band would sound like Kozmic Blues or CTA era Chicago, maybe some E-Street, Wallflowers in some songs, and MxPx or the Misfits in others.
Thank you, this is all really helpful, not snobbish at all.

That's kind of frustrating, the general compromises made to make a combo. Lemme be clear... my 'small rig' is currently the Genzler Magellan 800 and the Aggie DB112. It sounds amazing, it's my favorite setup so far, and if I need a bigger rig, I just add my GK Neo 212. But my projects have, as of late, been in more intimate settings, where space is minimal, and my back problems in the last year have taken a turn for the worse (isn't that a prerequisite for being on TB?), so I can afford it, so I might as well get a combo. If Genzler or Aguilar had a small combo, I'd already have it.

I still think I'm going to go MB, either that 500 watt Ninja Bona with the 212s or that model (can't remember the number) that's the 1 12 with the tweeter.

Really appreciate all of the input, from you and the others.

I did this last night. I was able to get some tones that were okay, but again, it just doesn't sound as good as I'm used too, and I do need something more compact regardless. Thanks.
 
Well, my middle age is creeping up on me, I'm getting tired of bringing my heavy but awesome Aguilar DB112 with separate head to practices, so I went and bought a Rumble 200.

All of my basses are custom high-end or at least pro quality (Wal, CB, Stambaugh, EBMM), and they're all 5's or 6's.

First impressions... whoa, I cannot believe how light this thing is, even moreso that it has a 15 in it. Will definitely be plenty loud, it's a bit bigger, dimensionally, than I would have liked, but considering I just dropped a grand on the EBMM, I couldn't go out and spend another grand on something smaller. So my back will surely like it. I don't know how the 100 would handle my low B, so I went with this.

Went through a few of the settings, generally, they sound good, but I have to say, I think my low B sounds pretty muddy and undefined, regardless of the bass (and the Wal has the best sounding B string in the universe, so it ain't the bass). Anyone else have this problem? I really don't want to send it back, but I use that string a lot. If you do have this problem, what approach do you use for the settings/eq?

I'm wondering if I should have either spent a bit more money or gone for the equivalent GK.
When I decided to downsize/reduce weight I tried various rigs, including Rumbles. I could never get a sound I liked from those, let alone get an even close to passable B string. And I have a Broughton HPF. I think I was spoiled by my heavy old hifi SWR SM400 amps and Eden D410XST cabs.

My solution was to bite the bullet and invest in a Mesa D-800+ (built in HPF) and a Genzler Bass Array 12-3 Slant. Gorgeous B string and a tonal range from credible B-15 to hifi. But yeah, about $2 Gs, you get what you pay for...

With the Mesa head I can scale all the way up to driving the two 410s if needed.

Hah, played an SM400 for almost 20 years! Miss that amp. I do think if I were to ever replace one of my bigger cabs, I'd seriously consider the Genzler, cuz I love the Magellan I have.

I don't know what it is about this amp. I've been playing with it all day, and I'm just not that into it. I wonder if I'm just really used to the hifi stuff.
It’s not just you. I just sold a Rumble 200 head for the same reason. Perfectly fine head, but I couldn’t get the tone I wanted out of it. The tone always sounded muddy compared to my other amps.

The Rumbles don't really cross the line into 'giggable' until the 500. YMMV.

Again, it depends on your volume requirements - I almost always DI into a PA, along with whatever amp I'm using - as long as the drummer isn't too heavy handed, I've done several hundred gigs with my 200... Also, I A/B'd the 200 and 500 quite a bit before deciding on one or the other - the volume differences between them wasn't as much as one would think...

The Rumble 200 and 500 use the same preamp. The low B string has a freq. of 31Hz. The lowest freq. mentioned about this particular preamp is 80Hz for the low tone control. The preamp may be able to create a freq. that is lower but it's going to be weak. Additionally, I can find no specs for the Eminence® Ceramic speaker. It's not likely that they would put a speaker in the cabinet that can go much below 80Hz. Any sound that you're hearing is the sub harmonics that the amp and speaker can reproduce.

When I was looking for a large combo bass amp the Peavey 500 was in the running along with the Ampeg BA-210. The reviews I read said that the Peavey was good for more like a 60's Rock type sound, plenty of mids but not a lot of lows. Obviously the Ampeg was well known for it's lows. Ampeg also specs their preamp at 40Hz for the low tone control. I bought the Ampeg. Since it had 2 10" speakers I wasn't putting a whole lot of faith in it's ability to get that low and I was right. I added a Celestion BL15-400X 8 ohm Green Label Bass Speaker that can drop to 40Hz into an extra cabinet and got the full 450 watts out of the amp. It goes low baby.

I own a Mesa D800 and pushed through my various cabs it sounds great. At a gig last month up in the cities, the sound guy said to me twice "nice amp" during & after check.

Having said that, I've always been able to coax a very nice B string tone out of my Rumble 500 combo. In fact I'm amazed what this little combo can accomplish tonally & volume wise with my 4 & 5 string basses. I love it. Plus it is very light in weight.

I own a Broughton HPF pedal but rarely use it.

Yeah, that's me. just bought a SR last week, which is why I didn't buy something better. lesson learned. Definition is key, for me, I'm more of a modern tone kinda guy.
Love my Rumble but I'm a 4 string guy. Not an expert and I am sure there are folks here that know way more than me. I have learned a few things for what it is worth. Old style Fender amps have a much looser (?) tone than something like an Ampeg SVT. If you like the sound of an old tube Bassman more than an SVT you are probably going to like the newer Rumbles. If you prefer a tighter sound this may not be the amp for you.
Life is too short to use equipment we don't like, get what sounds good to you.
 
If Genzler or Aguilar had a small combo, I'd already have it.

Genzler actually does make a couple of combos. Like the old Genz-Benz combos they mount the Genzler head on top of a cab with a cradle. See Magellan 350 Combo - Genzler Amplification for their small one.

I’m generally very happy with my Mark Bass CMD121P, though I haven’t used it with my 5-string in a year or so (mostly playing upright these days). It’s sure a joy for schlepping around, and I can always manage to get good sounds out of it. There are a couple of things that bug me about it: no mute switch, and the DI and other I/O are tucked away underneath the amp section in a very inconvenient way, but I can live with that.

You know, I saw the Genzler combo, I thought it was just a speaker and a head put together, which is what it is, apparently.
