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? 🧐



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. 😵‍💫
Not from those photos, no.

Ah, so I misread yours. Sorry. I seldom phrase things that way and my optimizing parser misfired.

Sorry, I read lots of things phrased that way and think it's concise. But I could be wrong. 🤪

OK, try ignoring the photos, and just use the block diagrams? Yes? 🤔
 
Darn, I thought G-Dog and Miles were going to, um, rumble. :laugh:
Seems more fitting if G-Dog and SharpCat rumbled!

How different are the 500c and 800c? Does the 800c not have the Rumble tone of its lower-powered siblings?
Same tone for both. 500: 350W internal, 800: 400W internal, so not much louder volume without a second cab. 800c has 1/4 power switch for smaller venues, and is 7 pounds lighter. Worth the extra cost, IMHO.

It is believed that they have the same, or very similar, pre-amp to generate the same, or very similar tones. And, of course, they have different power amps.

But, the R500c has ceramic ferrite magnet speakers while the R800c has Neodymium magnet speakers. While this accounts for the R800c being 7.5 lb.s lighter, some say this also makes the R800c sound brighter, or more articulate, than the R500c at similar settings. Some of those say they can re-EQ very close to the R500c tone, others not so much.

Bottom line is: you must see for yourself, for your "taste".

How does this work? Do I just jump in with my question? Ok What is the smallest Rumble that would work well in a small church (50 people, often less, think small country church) with a piano, singer, acoustic guitar and P Bass, no drums? Thanks

Sure, Danny! That'll work. Welcome to TalkBass and The Club. Do you have a Rumble yet? We'd be happy to bestow a free membership upon you if you do. Just tell us which one you have. If not, we're glad to help you shop with any questions you may have.

That's quite subjective, Dan. That combo of instruments could play at quite a range of volume levels. It's possible that a Rumble 15 or 25 might oftentimes be plenty, but maybe not always.

From my experience in exactly that situation, I would recommend nothing less than the Rumble 40. I use a Rumble Studio 40 to great effect! It will be more than you need in most soft songs/hymns, so just turn down. But when that li'l church in the wild wood really feels The Spirit you'll be glad your li'l Rumble 40 has the power to not just keep up, but drive the beat! 😇

Or, if your ears can hear the difference between the 10" & 12" speakers (and/or prefer 12"), the Rumble 100 would have even more power for those special musical events, like some revivals can become, or if you might occasionally jam with more secular (loud) groups. And it can turn down for church, just like my R500c does so well! And the 100 is not much more weight than the 40. See the Rumble Summary Info chart for comparisons.

😂😂 Yes, I have a Rumble 500. Which would work fine turned down but I was wondering if a 40 would be plenty. The 500 is kind of heavy. Don’t ask me why I bought it, it’s more than I’ll ever need, but I do stuff like that. I also have a Rumble 15 but it doesn’t seem to be super great at any higher volume. Thanks for the reply. Most likely just lug the 500, might as well earn its keep. Not that I would get paid and I shouldn’t because I’m not talented. 😂😂

@SharpCat - The 1/4 power switch is one of the main reasons I'm looking at the 800 vs the 500.

@G-Dog - Does the 10/2/2/10 flat EQ settings, as measured on the 500c, still apply to the 800c or does the different power amp and speaker magnets change anything? -the Rumble Club is like amp school for me and I love it-

Whether the R40 would work depends on several things - the piano player's volume, the singer's volume in the PA, size of room, acoustics, etc. An R40 might well do it. An R100 would absolutely do it. Our church meets in a small event center. We probably have ~50 people most Sundays with room for 70(?). But it's mostly reflective surfaces. I actually have to turn my R100 down a bit from my practice volume at home[1] because the practice room has lots of sound-absorption[2]. I actually use two daisy-chained R100s, but that's because (a) two sound even better than one and (b) I like having a spare just in case one acts up.[3]

[1] Gain: noon, switches: off, OD: off, EQ: flat per Rumble Club wiki, Master: 9 o'clock
[2] Not by design; it just has a lot of stuff in it and on the walls, as well as thick carpet
[3] I would want the same with any amp.

Ding, Ding, Ding! We have a winner!!! @Dan1985, you are now member #1803 in the Fender Rumble Club. Congratulations and welcome. Please 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.

Dan, if your church is secure enough, and accessible enough, to leave the R500c there semi-permanently that could help. I've done that before. Otherwise, it looks like the R40 or R100 is your Huckleberry.

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

Rumble On!
