Fender Rumble Club

I'm a keyboard player and a new convert. The Rumble 40, or even better a pair of Rumble 40 amps for stereo, with Baslite 2010 speakers, are great for Organ and Fender Rhodes electric piano. Deep lows and smooth mids, no god-awful horn or tweeter screaming at you. And only 17 pounds, my back owes Fender a lot of love. Keyboard players are unaware of this amp, I will try to spread the word. The Rumble 40 is far better at this job than the "full range" Roland KC keyboard amp crap.

I want to put traditional Black Silver Skirted screw on knobs on my Rumble .
Does anyone know if they will work?

Are the Rumble Version 3 knobs 1/4" or 6mm ?
If a knob is not a D shaft type will it slip?

@abath07, you should checkout the Fender Rumble Modifications section of the Rumble Wiki page for the "Blackface it" mod by Kevins1701.

HTH :)

BLACKFACE IT!

I like my Rumble 500 Combo, but it had a little cosmetic dissonance going. Fender borrows styling details from various eras of its history for these amps, but to my eye black Tolex and silver grille cloth recall the classic mid-'60s look. And the flat logo, cutout corners and cream knobs didn't hang with that. The handle also looked a little foreign. Turns out they're all easily and cheaply fixed, using genuine Fender parts, and the changes are all reversible.

The signature lipped corners to use are the "flat" ones, without the dished screw holes, Fender part #0991348000. They like one of their screws in a slightly different spot, and they're shaped for slightly thicker cabinet lumber, but I like the change. I looked at lots of pictures of '60s Fender amps to get the right orientation of the Blackface logo (#0994093000), and of course, logo placement from the factory was all over the map! The skirted 1-10 knobs (the small ones, 7/8-inch across the base, #0054419049, not the common 1-3/16 size) push right on to the Rumble pot shafts. I oriented mine with the mid-point ("5.5") straight up beneath the control label. Finally, the proper Blackface handle (#0990947000) fits right on using the original Rumble screws.

I have a set of tilt-back legs (the large, 19-inch size, #0990713000) and they will probably go on eventually. But those change the rules by requiring holes drilled in the amp sides. For now, the better integrated Blackface theme makes me smile.
What are you talking about here: "The signature lipped corners to use are the "flat" ones, without the dished screw holes, Fender part #0991348000." It's hard to see a difference in the pix. Do you have any more pix you could send? Thanks!

Got the 500 head in yesterday. Set it up with my 210 cab. So far, so good. I am diggin it! Still playing with the knobs... getting close!

I really didn't need/want the 800 and wanted to get a 500 before they were all gone.

I did the same thing. I impulse bought the Rumble 500 before I couldn't get one new. I started off hating it. Then started to like. Then I dismissed it again and now Im happy with it. Again....LOL.

I have been trying to compare the Rumble 500 to the Rumble 350 through the Rumble 115 cab...Its a head scratcher for sure. I get worn out getting up and switching things around and I also get tone overload. When I play with the band, I like both heads. They are both different. Alone though, I like the 500. I also have a Littlemark II that I like to compare and an RS 210 cab. But Sticking to the Rumble, I think I prefer the 500. Its more versatile and more fun really.
The 350 is very good and the sweepable mids knob is enjoyable too and with the band the 350 brings more discipline and its a little flatter if not Fatter. Recorded, I like the 500 much better with the band. I was going to return it but for now I'm just going to keep everything and just try to really zone in on what I like best. I mean, every room is different and I play in different rooms with the band so tone chasing for any use beyond playing alone in my house may be fruitless and most people listening in a bar don't care. It doesn't translate in their ear I think. So I don't know if it'll matter much to me when we gig. But at home I can focus on cool tones. i'm sure I'll never settle for just one 'tone' for very long. And this is leading me to thinking about getting a Rumble 100 for gigs. Light and easy to use.
 
FYI, Rumble Studio 40 owners! Those lucky (rich) Rumble Stage 800 owners got the 4-button footswitch included with their amp. But not us Studio owners! It's an extra-cost "option" for us!! But, it enables convenient remote foot control of several functions, including the built-in tuner, amp preset selection, Setlist preset selection, Quick Access preset selection, effects bypass, 60-second looper and more. The more you use the features of the Rumble Studio, the less optional the footswitch becomes. :(

So, do you wanna save a few bucks on the 4-button Fender MGT-4 footswitch that makes so many of the features of these cool bass amps easier? Find an old Fender ULT-4 footswitch made for the Fender B-DEC & G-DEC amps, or an old Fender MS-4 footswitch made for the older Fender Mustang amps. They are electronically identical and will work just like the MGT-4, only they can be bought used for a lot less $$. :)

Yeah, well the button labels are a bit different, and that can be a little confusing. Not to worry, Fender has that covered. :smug: You can Invalid Link Removed to print a button label overlay that will update the older footswitch to the new terminology to make it look like this:

MGT-4 Footswitch paper overlay.jpg

Well, Yours will probably look better than this. I was too impatient to cut the hole edges very neatly. And I couldn't find my hole punch to uncover all those little lights! But that's better, right? Now you can follow the manual instructions for how to use the footswitch. Just be careful not to crease or tear the paper with your foot!

But, wait! There's more!! Invalid Link Removed to stick onto the older footswitch for a more secure, better looking button label update. (Or easily remove it for use with the older amp(s).) There, now, doesn't that look better? And it's much sturdier than the paper version. [*While supplies last.] But, hurry! Act now, before supplies are gone! Just Invalid Link Removed, and give them your mailing address, to request your Magnetic MGT-4 Overlay. :D

I hope this helps some worthy Fender Rumble Studio owners! :thumbsup:

I know these aren't what you mentioned but I like them.1020181039-00.jpg 4 of the new with 2 of the original. Got 'em on Amazon.1020181046-00.jpg

Here's a link to the Invalid Link Removed corner he references for his Blackfaced Rumble. The main difference I see is this one he uses covers more of the front side of the corner than the stock corner does.

Good decision!

I have a BA-108. Don't use it. But it has two little features that are nice: the tilt-back wedge-shaped case, and the volume control on the Aux input.

I'll be Craigslisting it at some point.


I had zero qualms with the Ampeg. I actually had a B-15 flip in the 60's. I bought a Fretless and love the low volume clairity and Boomer bass tone on the Rumble, 25w...8"...amazing.

Ok. Cool. Now I can tell. I like the vintage ones! Thanks!

FYI, Rumble Studio 40 owners!

A local bass player went into the Fender dealer to try a Studio 40 & the complaint was that they didn't have the foot-switch.
I pointed out that the MGT-4 they had connected to their Mustang GT amp in the back would have worked. It still surprises me they didn't know this.

I seriously considered buying a Mustang GT for the pedal/foot-switch compatibility, but TBH our VOXs sound better.

So I tossed my old headphones down onto the carpet next to my amp this afternoon, as I've done many times without a second thought. Went to use them a minute ago and the right one is shot. Loose and rattling inside.
Looking for decent headphones now on amazon and losing my mind! Far too many choices.
What are you guys using with good bass response and no distortion? Kind of used to sealed back, over ear but looking at semi- open over ear. I want to stay under $100 if possible, I don't record, only practice with them.

If you use sealed back/over ear, you can ignore distractions-like being asked to take out the trash, answer the phone, etc.:rolleyes:

I've been using Sony MDR-7506 headphones since 1997. Bass response is tight, they are pretty much bullet-proof, and the impedance is 63 ohms, exceeding the 32-ohm minimum specified in the Rumble manual. These came from my studio days and I am still using my original pair, having replaced only the ear cushions. I upgraded the deteriorating pleather to the plush Beyer replacements. You should be able to find a pair at around your price-point.
