Fender Rumble Club

No, I don't think so, not for any useful length of time. It would take a heck of a lot more than just another output jack to make the 800 combos stable at 2.0 ohms! The combos do NOT have all the same guts as the 800 head. Maybe the same pre-amps (except the Stage), but definitely not the same power amps and outputs. 🫨

I can't find it right now but, I once read agedhorse list several differences, all requiring very high quality components, that are involved between 2.67 ohm and stable 2.0 ohm amps. The only one I could think of was heat management, but he said that was way down the list. There's a reason why the 800 combo costs only $100 more than the 800 head. You don't get two neo speakers and a tuned cab for just $100. There's probably at least another couple hundred to get the head's stable 2.0 ohm power. Like even just the Impedance switches are different; both go from 8/4 ohm total, but one goes to 2.67 and the other goes to 2.0! Apparently it's a much bigger difference than the numbers make it look. 🧐
I also depends on the cabs that you have hooked up.

There is a complex circuit involved when driving most loudspeakers and the ratings are almost all approximations.

A driver's impedance will change with frequency as well as how hard they are working (impacted by heat).

Some cabinets are rated for 8 or 4 Ohms while their minimum impedance might be very low.

Put 3 or 4 cabs in parallel that have a low minimum impedance and it's a much more difficult load for most amplifiers.

I don't believe an amp's minimum stable Impedance depends on the cabs you have hooked up. Your cab combinations merely determine if you are on the safe side of that minimum, or not.

I wasn't implying that the amp's stability changes based on the cabs (at least, I did not mean to imply that).

Any given amplifier's stability is what is it is, but yes, certain cabs present more difficult loads that may not be evident from a simple impedance rating.

Most amp makers want to be on the safe side of things, if you have cabs that operate closer to their nominal rating then it is less likely to cause the amp to go into protect mode.

To give an example - Genzler rates their amps down to 2.67 Ohm, but because of their own speaker cabinet design, they say their amps will work with their cabs connected in any way that results in a 2 Ohm nominal load - i.e. four 8 Ohm cabinets or two 4 Ohm cabinets, ... etc.

I think there may be a few other manufacturers who do the same when the system is all their equipment.

How hard the system is pushed is another consideration.

Not to mention that class D amplifiers don't need/have those big old transformers to match speaker impedance.
Also the class D circuits like the ones used in rumbles (AFAIK, take it with a grain of salt, etc.) are limited/regulated by their power supply's voltage (e.g. in the original - internally 8 Ohm - r100 combo, the poweramp chip could do up to ~300Watts by spec, but limited to ~100W by their supplied voltage).

I am also not implying that anyone should use speakers that are out of spec! Please, don't do that unless You know the possible consequences! (they no workie if magic smoke comes outie)

Just saying that class D amps are versatile in general and - mostly - more resilient/protected than the old transformer-coupled ones.
 
Py, are you asking about the Rumble V3 Stage 800 modeling combo, the Rumble V3 800 combo or the Rumble V3 800 HD head? Both combos can do 2.67 ohms, as discussed above. But the head can do 2.0 ohms!!

Do you have a Rumble, or considering getting one?
The Rumble V3 800 combo is a go for me and soon. It just fits the bill for everything I do these days. I have a big rig that I really like, but the majority of the shows I do anymore are medium-sized rooms always w/ FOH support. My question had more to do w/ pairing it w/ cabs I have and/or cabs I know are at the gigs usually. The guitar players in my band are loud-ish but I figure the Rumble 800 will keep up just fine. I appreciate the speedy responses and all of you being such a positive and supportive group!

Arrrr, pyrat! @pyrat56host, you are now member #1848 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.

Oh, yeah, the Rumble 800 will most definitely more than keep up with loud-ish guitar players, drummers & heavy handed keyboardists. That's what I got my Rumble 500 combo for 11 years ago, and it really did the trick!! And, it's just possible, like in my case, that you won't even need any extension cab(s) for a lot of gigs! 😉

How about telling us a bit about yourself, py, 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 ... ... ...

How kind of you to assign me a number! I've been playing for close to 50 yrs. I started out in Colorado playing hard rock and punk (very early adopter) and eventually jazz. I moved to Hollywood to go to music school and fell into the L A scene playing hard rock. The wild life lead me to Minneapolis and eventually my band (the Loose Rails) that I've played w/ for 35 years. Lots of road experience and many gigs...now primarily doing shows a few times a year at most. I've always been a huge Fender fan and player over the years...and now I'm happy to gig my P-bass and Rumble...the rest of the "collection" is getting sold off or doled out to the grandkids~

After many years as a part time bass player (guitar player) just playing bass at home through plugins, I am now in an actual band with upcoming gigs. I just picked up a Rumble 500 that seemed to fit the bill. Who knew an actual amp in a room was so AWESOME (like everybody dude...). :-)

Howdy, Den! @Dennis99, you are now member #1849 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.

Congratulations, too, on joining the band! Nothing beats making music with others. And nothing handles those bass duties better than the 7ender Rumble of your choice. Although, I happen to believe the Rumble 500 combo, like my own 11-year-old one, is certainly a sweet spot of power, weight and cost for those duties. 👍

Barb played at our monthly concert at work today. ... ... ...

A. 'Sounds' like a very cool place to work! (Get it? 🤩 hee hee)
2. Are they hiring?​
π. Is this Barb?

... ... ... The bass player (Wyatt?) played a Jazz bass through a Rumble 40 with the tone controls all at 12, DI to FOH. It sounded great.

And, for all my innerwebs sooper sloothing skilz, I could not find the name of her bassist anywears! Is this a pic of him/them? All I could find out about him was in that linked article where she says he left the band she got kicked out of to stay with her!?!

Yeah, I had searched before posting. Dude's elusive, or at least his name is. And yeah, that's them although his hair is about half that long now. Cool band, cool peeps.

Our official motto is "Cirrus rocks!" We are well taken care of, and we support the local music scene in various ways - which happens to result in the company getting tickets to various acts at the Moody Theater (Austin City Limits TV show, mainly), occasionally at other venues, and SXSW and ACL Fest - for which you can put your name into a virtual hat for a drawing.

So it sounds like you are right!

Do a search on that large online retailer for “colorful zipper pulls”. You can get a huge pile of the nylon string type for like $10. Loop them through the zipper tabs and you’re done. I just grabbed some glow in the dark ones myself.
THAT's what I'm talkin' about! Thanks again @SharpCat . These colorful zipper pulls warrant a medal of honor, or at least recognition from AARP. Now I can see where the damn zippers are.

Hello fellow Rumblers! I need some assistance.

I damaged the input jack of my Rumble 500 combo. All cables from my bass no longer connect through that jack. A friend has removed the jack. It’s a five piece part.

Do you know where I can find that particular piece, in order to replace it? I live in Montreal, Canada. No one around here seems to have it.

If it’s not findable, do you know if it’s possible to buy a new board for the Rumble 500? I’d hate to do that, but I also don’t want to throw out the amp.

Thanks so much

jf, the Rumble Modifications section of your Rumble Club Wiki page has a link to an input jack replacement posted here before. Does that look like what your friend removed? If your friend can't solder the new one in, it may be worth getting an actual amp tech to do it. Heck he might even can get the part cheaper, too!

Wow, thanks for your help. It’s not the same piece though. The solder points are underneath the jack, not on the side. And there’s five solder points. It’s closer to this, but not quite. Fender Jack 1/4" PCB 2/CD SCC 0030771000. That part has three solder points, I need five. I’ve included a pic of what mine looks like.

Weird, I guess Fender started using a new jack at some point. And I can’t find it anywhere. If anyone does, please let me know. I’ve looked on the Fender site, they don’t seem to sell this.

I’ve found something similar from other companies. I’m a little apprehensive about going with someone else than Fender, I imagine the dimensions are different.

If anyone here has gone through this, I’d love to hear from you!

Do you have a good amp tech near you, preferably an Authorized Fender Service Center?
