Here's a link to an abridged performance of our group of seniors "performing" in October at our 55+ community clubhouse. I'm usually out of frame but you can seen my Rumble 100 and jazz bass head stock. iPhone video and recording.



We try and learn about 15 new songs for each bi-monthly performance. With 5-6 repeats.

I picked up a Rumble 100 combo last week for playing in the living room, and maybe some recording a bit in the future. Nice sounding amp. So light I can pick it up with one finger.

While the store employee was searching for the 100 I tried the 500 combo. Whoa, what a beast. Sadly for the small space I have it wasn't doable. I'm happy with the 100 so far though.

I hope one day I can use more than my pair of R100s!

Funzola! That was really great. Thanks for sharing this. Looks like everyone's having a great time.

Thank you John. We do have fun. Working on getting better...

And thank you to those that liked.

¡Hola, flexi! @Variflex, you are now member #1802 in the Fender Rumble Club. Congratulations and welcome to TalkBass and The Club! Put that number in your TalkBass Signature for safe keeping. Then make yourself at home here and on your Rumble Club Wiki page, the repository of all Rumbling wisdom and knowledge.

Just FYI, there are currently two versions of the Rumble 100 combo out in the wild, those with a Pre-/Post- switch by the XLR Out and those without. Which one do you have?

And how's about telling us a bit about yourself, such as your bass experience in general and your Rumble journey in particular? You'll fit right in here since we have all kinds. But we all love to ... ... ...

Rumble On!

Whoa. Thanks! Number #1802 it is! My 100 has the Pre/post switch by the XLR out. So new batch v3 according to your link.

I will confess, I've been playing guitar since '91. My brother picked up bass shortly after I started guitar. While he now lives halfway across the country he always keeps a bass here, a '92 MIM Jazz Bass. Lately I've found myself playing the J Bass more and more. Not wanting to ruin the speakers in my guitar amps I decided I needed a bass amp. I have my brother to thank for suggesting that I take a look at the Rumble.

My big guitar amps are set up in my basement but I wanted something small to play bass in my living room. I hadn't been to a Guitar Center in about a decade but found myself near one during a trip. Tried a Mark Bass CMB 121 (150w) and wasn't thrilled. Plugged into the Rumble 500 and wow, that was it! But it was huge for my living room. Tried the 100 and obviously it's not quite the 500 but still blew the CMB 121 out of the water. I tried an Ampeg Rocket as well but the Rumble 100 was the winner. I've been having a blast with it ever since I got it, sometimes with a few pedals, sometimes straight in.

You do show up in the video! Looks like a lot of fun. I like your cajon player. Brush, stick and cymbal. The cajon player in the 3 piece band we had for our Thanksgiving in France lunch played with just his hands, and left his wedding ring on. Good lord, but that was irritating. You did a fine job.

 

[terryj47]

Thank you LeMartien. I'll pass you comment on to Jim (cajon player)..

I don't take my wedding ring off - except for playing hand percussion instruments. It's bad for the instrument, my finger, and the sound, so into my pocket it goes.

Merry Rumble* Shopping Season!​

I assume that's where everybody is at that usually, but not lately, posts in the fora I frequent here on TalkBass. It's been pretty quiet here! I've been out in the hubbub myself, bub; but not shopping, just running a few miscellaneous errands. And, so far, the traffic isn't too frantic and people are still reasonably friendly. But it's still early yet. Please spread some joy in what remains of this year.

* Not that everyone is shopping for Rumbles, necessarily. But my Rumbles make me happy and that's the kind of shopping season I wish for all you Rumblers here.

Rumble On!​

Just busy. Getting busier. All good, whether peopley, bassy, bikey, or home repair stuff.

Thanks again, everyone, for suggesting I try DeOxit D5 on my crackling 200 combo. I took it apart yesterday to spray the pots and pushbuttons, and the gig last night went smoothly without any crackles – so far I am very happy indeed.

To get to the pots and switches, you need to disassemble quite a few parts. First, remove the black screws at the top (one on each side) and sides (two each) of the combo, and then take out the five screws along the bottom of the back panel. When sliding out the amp, you can simply disconnect the speaker by unplugging it: push the tab and pull the plug. You have now separated the amp from the speaker enclosure.

However, the PCB that holds the preamp is not directly accessible. To get to it, pull off the knobs and remove the nuts and washers of all the pots and the input jack. The preamp is then only held in place by four screws along its longer sides, two of which are hidden under a foam strip. To get the preamp out, you still need to move at least the PCB holding the jacks at the back (FX loop, aux in, headphones, DI out, footswitch) and the small PCB for the external speaker out of the way. These are each held in place by the nuts around the jacks, two screws next to the XLR jack and one screw each from the pcb side. Once those two parts are loosened, you have enough wiggle room to pull out the preamp.

From there it is really easy to apply the d5 and reassemble the combo.

Well done. I'm glad it worked out. Happy Rumbling.

Always a good thing to learn how to work on your own gear. Congrats!

With what's printed on the preamp board, this should be proof that all the Rumbles, R40 through the R500, use the same preamp. Consistency of sound and simplicity of production for the whole line of amps. Any wonder why they all sound so similar. I have a feeling, the components for the "RUMBLE 200 & 500 ONLY" are likely on the the preamp boards for the R40 and R100. (These look like they might be the variable fan speed control components, as that is the different components on the 200 & 500.)

The differences that are present is in the power output modules and the speakers and then I don't foresee any great differences in the power modules, as class D amp modules usually reproduce what they receive pretty accurately.

Good eye, Jack! "RUMBLE 40-500 V3 CONTROL PCB", indeed!! And, yes, the Variable Speed Fan Control is the only thing on the R40-500 Block Diagram that says "RUMBLE 500/200 ONLY", so that makes sense, too.

But, it begs the question, where on the R40-500 Block Diagram does the preamp end, if the Fan Control is on it? And just what all on that diagram would be on the Control PCB. Indeed, might some of the preamp functions be on another PCB, like the "move these ..." in the photos, instead of the Control PCB?

And, assuming the "New Batch" of R100s is more like the R800c Block Diagram, where does the preamp end on that?

And, according to one of our Rumble Talks, the 40 & 100 have a class AB power amp & class D power amp, respectively, while the 200 & 500 have class D ICEpower modules. And, according to the manual, the 40 & 100 power amps are only 8 ohm capable, while the 200 & 500 power amps are 4 ohm capable.

But, according to the "New Batch R100s" addendum, those are "built with an alternate power supply and amplifier module" that is not specified. So, there's no telling what they are capable of!

Things that make you go "hmmm..."

You misread that Rumble talk or someone’s messing with you. It says the 100 is class D with a custom switched mode power supply. The 25 and 40 are class AB.

Also, the lower right PCB is the power supply. The lower left PCB should be the amplifier section. Does it contain preamp functions? No idea from the pics.

I believe my saying "the 40 & 100 have a class AB power amp & class D power amp, respectively" means the same thing, does it not? And the 40 & 100 both have a custom SMPS, so I didn't mention that. Where did I go wrong? ​

Also, the lower right PCB is the power supply. The lower left PCB should be the amplifier section. Does it contain preamp functions? No idea from the pics.

Well then, care to take a stab at literally "drawing the line" between preamp & power amp functions on the block diagrams? I think the controls, or pots, are obviously pre-, but I dunno which "side" the headphones, line out & Delta-Comp™ would be. But I would have expected the Fan Speed to be part of the power amp, except it's on the Controls PCB! But then, I don't suppose the PCBs have to be strictly either/or, but could possibly have both functions? So, obviously I have no real idea where, much less why, to draw the line. ​

Have you A/B'd their manuals yet?

Rumble 40, 100, 200 & 500​

​

Rocket Bass RB-108, 110, 112, 115, 210​

I looked but did not find a manual for the R800c.

Can you tell me where to find it?
