That's right. As long as one of the amps has an effects loop, it works fine. So the 100 can be paired with the 40, but two 40s cannot be paired with each other.per JohnBjr (#15582), Effects out jack from the 100 to the input of the 40, right?

I see. Thank you. Pity the 40 doesn't have the effects loop.
I love the sound of the Rumbles but the only thing putting me off at the moment is the direct out is not balanced, so any volume adjustments on stage will affect the FOH. Maybe I should just use a seperate DI - but thats more money and something extra to pack along. I'm deciding between the Rumble 100 (with a possible 40) and the TC BG20 210. I like the mute function, tuner, and balanced DI on the TC but prefer the tone of the Rumble.

I wouldn't worry too much. I'm sure I asked a similar question some pages back and was told to use a dummy plug into the headphone jack to cut output to the speaker.I see. Thank you. Pity the 40 doesn't have the effects loop.

I think I'll bring what I got.It sounds like in the long run you need a bigger sound board, but immediately 1) if you're playing to a lot of seniors, plan on being loud-I do a seniors thing weekly; believe me! 2) If your outdoors especially in the open or on a roof, bring your big guns! Accordions and saxes cut through and run over anything! 3) I run a Rumble 500 cab through a 115 and 410 outdoors and never had complaints; volume nob works and disconnect a speaker if needed. Bring what ya got and plan on being versatile!

After reading the last page or two, yall are chaining two Rumble combos together like what sounds to me like the gallien Krueger MB & MBP. My question is can you use extension cabs while chaining the rumbles together or just the combos alone?
Thank you sir , I'm a bit intellectually challenged with this stuff, but now knowing I can now have a thousand watts & 8 tens I have a dream !!!!Yes you can have extension cabs with chained combos.
You could end up with 1,000 watts into 8 10" speakers, for example.
Just to be clear on all this chaining stuff, here's a section from the Fender Bassman 500 amplifier head manual:
![]()
Fender explicitly says that PREAMP OUT / POWER AMP IN (what is called the EFFECTS LOOP on the Rumbles) can be used for either an EFFECTS LOOP or to chain two amps together in a master/slave setup.
Here's the block diagram of the Rumble v3 40-500 amps:
![]()
Notice in this block diagram, when you plug into FX RETURN, you disconnect the preamp/tone section from the power amp/speakers. Plugging into FX SEND does not disconnect anything.
And in case it wasn't clear, here's how you chain two combos:

They aren't better just different and of course more expensive. The Mesa D-800 and Genzler Magellan 800 are no better than the new Bassman 800.are the more expensive "boutique" brands only 10-15% "better" tone/feature/flexibility wise for 75% or more the cost? Im not willing to pay nearly double for just a little bit of returnI would love to hear from folks who have replaced "high end" brands with a Rumble,
+You could chain a pair of Rumble 500 heads together and run four Rumble 410 cabinets for 1,000 watts and 16 tens!![]()



Thanks..I to agree that MarkBass is overpriced, especially for your avg. "working man" bass player.They aren't better just different and of course more expensive. The Mesa D-800 and Genzler Magellan 800 are no better than the new Bassman 800.
It's up to you to buy what sounds best to you. MarkBass is just overpriced, and is neither better nor boutique. If Fender Rumble is the Ford of bass amps then GK is the Chevy and Hartke is Dodge.
I've been throughTo all the Rumblers out there:
As mentioned in an earlier post, I am getting pretty close to pulling the trigger on a Rumble rig(500 head and 210 cab).
I wont have many opportunities in my life to get a new rig and am having second thoughts about maybe looking at so called "higher end" brands like Aguilar, Mesa, Mark, etc.
My question is: The v3 Rumble get's such good reviews but cost so much less than other brands...it leaves me wondering do the heads that cost nearly twice what the rumble does actually sound that much better? For example(totally subjective i know), are the more expensive "boutique" brands only 10-15% "better" tone/feature/flexibility wise for 75% or more the cost? Im not willing to pay nearly double for just a little bit of returnI would love to hear from folks who have replaced "high end" brands with a Rumble, it would ease my worries a bit...
