Fender Rumble Club

So in the interests of more Rumble education, if gain is set to zero ie off then is the preamp essentially bypassed and the "sound" produced only by the power amp? Yet another nice Rumble "stock" sound, by the way.


These are my settings. Bright and contour switches on. Gain is at zero.

Sounds mega and punchy to me. Replacing the "gain" knob with the dirt level/section.

Thanks for the reply. That's what i would think. I'll give them a try though. It would be interesting to measure, but i cannot do that myself. I must say that i was suprised to learn that the 'flat settings' on a rumble (all knobs at noon) arent flat...lol

Few guitar/bass amps are actually flat with all tone knobs at noon, but some are definitely flatter.

No. The gain knob works more like the input gain switch/knob/slider on an audio mixer input channel. It gives you a range of input attenuation (cut). All the way up assumes you have a weak-ish signal coming in that needs all the gain it can get (or on an amp, it can also mean you want to overdrive the input). All the way down is for hot signals, to help you not overdrive the input. In between is for ... in between.
 
Got it, thanks. When i played a P bass i liked sound with gain around 9-10. But with my [passive] J bass the stock pickups are indeed weak-ish so boosting Gain to around 2-3 really nicely juices up the sound.

Yeh I started with these settings which you posted. These are the "flat" settings on the rumble and then I adjusted them a little. I am using a Gibson non reverse thunderbird bass for reference and I've backed off the pick up volumes to tame the dirt a bit but it's still there.

Not much drive there. I'll try that tomorrow.

No, T, aside from using their ears, the 800 HD & 800 combo users don't have equivalent frequency curves to refer to. But, it's fair to believe that they have the same preamp and pots as the 500, and the differences are elsewhere. So the freqs should be very similar, at least. :thumbsup:
.

I hope someone can do a spectrometer analysis on the 800 as well .

Got the ‘72 out tonight. Pumping through my Sadowsky preamp and Fender Rumble 800.

You've seen the cartoon of Batman slapping Robin and saying, "It's a Gain control, not a Volume control!", right. Well, that's the case with Rumbles. Here's what the manual says:

Note the interactive affect with the Vintage voice button and the Overdrive!

HTH.

The Gain knob on Rumble V3 work like compressor to me. Beside tighten up entire bass tone, she also remove some boomy on E string and meaty up G string tone in some degree. Work best while Vintage + bright button engage.
 
My Ampeg RB112 has defective knob on SGT section after 3 months evenv from repair/replace under warranty.

Email Yamapeg and they reply me " It is a mechanical part, it can fail. Regarding quality, we sell a lot of product. A few failures of a mechanical part does not justify an investigation by our Quality Team. If there are a considerable number of failures our Quality Team, of which I am a member gets involved"

Sound like they don't want try to fix the problem on my view.

If Yamapeg ignore that simple issue ( defective pot ), i will return back to Rumble world again.

I definitely notice some compression on my settings with gain at zero and vintage switch off. Only slight but it is there. Like other drive pedal's, the drive gives some compression at least to my ears. I did wonder if there was a built-in limiter in the rumble too.
 
Yeah, they cleverly hide it in plain sight in the Rumble 40-500 manual:

But it's not new or exclusive to Rumbles, it's been around a very long time on many various Fender amps. Although not necessarily the first instance in print, this description is from the Fender M-80 Bass amp manual over 30 years ago, which had a Delta-Comp on-off button on front!

Simply put, it is a dynamic compressor that responds to clipping by limiting the distortion.

Consult your Rumble manual, your Rumble Wiki Rumble Talks, and my previous post copied here, and wonder no more. :cool:

I have a Rumble 100 V3 and noticed lately that the volume knob is sometimes scratchy between 0 and quarter of the way up. I also noticed the amp seems to sometimes sounds more darker then normal and other times it sounds brighter. This is with nothing changing. I don't use the bright, vintage or contour switch. Is this a known issue?
 
This is my first Fender amp. It is the rumble 100w. Have read alot of good things. Got this amp used and well below market value. Only used about ten times.

Yay! It's Twofer T... uh, Wednesday! :confused: @Adam John, you are now member #1656 in the Fender Rumble Club. And @ics1974, you are now member #1657 in the Fender Rumble Club. Congratulations and welcome. Please put those numbers in your TalkBass Signatures for safe keeping. Then make yourselves at home here and on your Rumble Club Wiki page, the repository of all Rumbling wisdom and knowledge.

Adam, I hope that bargain serves you well and long. ics, those are not common issues, but occasional scratchy pots do happen on most brands. Often just several quick turns back and forth cleans them up. The darker/brighter sounds is a new one on me! Hopefully, your unit is still in the 2-year warranty period, if you want to get a free check-up by a Fender Authorized Service Center after contacting them with video evidence of the problem(s).

Meanwhile, Adam & ics, how about telling us a bit about yourselves, such as your bass experience in general and your Rumble journey in particular? We have all kinds here so you're bound to fit right in. But we all love to ... ... ...

Rumble On!
