Fender Rumble Club

Does running the amp at 1/4 output get you anything over just turning down the gain and master? Sounds to me like it works like a governor.


I would think the Low setting of the 1/4 Output Switch allows you to drive the DeltaComp circuit at a lower volume and gets you "more tube-like response" than if you just turned down the Gain and Master. So, you can use a higher Master setting at the Low Output level to get more growl. At least I think that's the intention.

From the R800c manual: "H. MASTER: Controls overall amp volume. When setting MASTER higher or playing more aggressively, modified Fender DeltaComp™ limiter circuitry delivers more tube-like response to speakers with greater compression, harmonics and sustain."

Agreed!

Cool, Silbo! I've got a G-DEC 30 also! I got it just before I got my 7ender B-DEC 30, which is just tons o' fun with the modeling and drums, too!! :cool:




Yep, "way back in my day" 50 or 100 RMS watts was about as much as you could get, with 15, 22, and 30 RMS watts for guitar amps being much more common. But even back then they advertised peak watts when the RMS wattage numbers seemed too small. But, actually, watts are watts, whether tube or solid state. Its the testing & rating method giving RMS (like Continuous) or peak (like Program) that confuses things, along with the psycho-acoustics of tubes vs solid state.

Now we know that bass frequencies need a lot more power to be heard cleanly, about 4 times as much, than guitar frequencies do. So, the most popular bass amps usually have more power than most guitar amps, even back then. It's just that more powerful amps are more common these days, though you don't see guitar amps going for the higher wattages so much. ;)

I was constantly amazed at how much noise(good noise)I got outta my 63 piggyback Bassman, which was ~45W(?), through that one-sometimes 2-2x12 cab.
[still waiting for the 'rumored' 2x12 Rumble cab]

So far, the Rumble 212 cab is still just one of our collective Rumble Fantasies. :oops: And now we can probably add the Rumble Neo 210 cab, which just looks like the regular 210!

Yeah, I kid about it. I have no need for any extension cab-thus why I sold my R112 a few years ago.
BTW, all that "good" noise I was producing through the 63 Bassman was with a Gibson EB-3, Mudbucker only.
I remember my settings on the amp: Volume: ~4-5(1-10 scale, not 'clock'), Treble: ~4, Bass: 10, Presence: 10. Similar settings will NOT work on a Rumble, though I do use the BRIGHT button as presence-sorta.
 
Just received my Rumble 800c. First impressions, it’s unbelievably light!
I wasn’t expecting a foot switch, so that’s a bonus. Sound wise, only had a quick 5 mins, so hard to say. But, it sounds loud and clear. I like the presets, would be nice if they had LED indicators like drive to show they’re engaged. I don’t think I’d use them at gig volume, and it benefits from a slight cut in the bass EQ!
I couldn’t clip the preamp with gain at full on my passive Yamaha BB.

I had a Stage 800 when they came out, but soon switched to IEM and Helix. I also spent a lot of time fiddling with it and never really settling on a core tone. Glad I went for the Rumble 800 this time around.
 
Update to the above (R800c)… turned it up to “gig volume”, ie 50% gain and master in full power setting and it’s obnoxiously loud! To be honest, I can’t see myself pushing it that hard at a reasonable sized gig.
Still can’t clip the preamp, I maxed everything and still no orange light. My bass is a BB P35, passive PJ, fairly low output I guess.
 
Just bought a used Rumble 200 a couple days ago. Love it! Before all I had was an Ampeg BA-108. Can I join the Rumble Club?


Yes! Yes, you can, Manly. @Mannish, you are now member #1706 in the Fender Rumble Club. Congratulations and welcome. 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.

How about telling us a bit about yourself, Manny, 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!

Hi, Rumbler #1036. Welcome back. Perhaps you'd like to add a visual indicator to the 3 voicing buttons, like @Flippy did! :thumbsup:

May I ask if you've had the opportunity to play in a "bedroom / small practice" or otherwise "quiet" situation, using the low-power mode yet, or to update us with your experience when you have?

I'm curious to know whether it can really go all the way from bedroom to large gig using that setting, or whether there's simply no adjustment available in terms of power / EQ when you play it quietly (e.g. is there any kind of low volume available before it's "off")?

This is really the only thing stopping me from ordering one now - no matter how loud it might go, I have to know I can play one quietly too...

Altho the appropriate metaphor is probably "hill" rather than "step," let me say the next step up from "off" in the volume is "quiet."
