How the combo can be destroyed if the power is off ? In my supposition, only the head is on...
Oh yes, that's a nut question... There are so many people in this forum... I think quite everything has been experimented.

OK, No you can't use a Rumble combo as a passive speaker cabinet.

Thanks, sorry for my nut question... I found a lot of silly things about that !

You had the master volume at 4 oclock?!?! That must of been hella loud!!! If we're talking clock face 4.

No kidding! I have never had to have mine past 11 o'clock... That's with two guitars and a drummer who thinks he's gotta kill em.

No doubt. I had mine at 11 o'clock for last week's gig, and it was LOUD.

Sorry! You are all right--I was seeing it as a dial from 0 to 10, with zero at the bottom, but then I used "o'clock", which would have made it more like 10:30 or so!

It depends on the actual combo. For the V3 Fender Rumble you need to input your signal through the instrument input jack in order to have any control of volume. If you go into the effects return you'll get full power with no control.
As for turning it into a passive unpowered cabinet, no. If you input a powered signal from another source into the effects return jack you will destroy the combo utterly.

I know for the current Bassman series, this is explicitly OK to do:

Is there a reason this would not work on a Rumble?

I was told you have NO control of the volume, but I have no real experience.

 

[Lionel Albert]

This is a video I found, it's a bit long but interesting.

Not on the slave side; the slave gets all tonal and volume control from your master combo.

Typically, all signal control is in the pre-amp, the power-amp (ICEpower module, in this case) does nothing more than amplify what is coming from the pre-amp. The block diagram for the v3 Rumble 100/200/500 shows this to be the case. Master Volume -> Contour filters -> EQ -> FX-Send and FX-Return.

It looks like if you feed a Rumble 100/200/500 combo FX-return (slave) with a Rumble 100/200/500 combo FX-send (master) the results would be the same as if you spit your instrument input cable into the input jacks of both amplifiers which had all the knobs and buttons set identically.

I know it looks that way on paper @Scott Truesdell, and that is exactly the way I thought it was, but others have tried and said no that's not the way it is. So just experiment and find out for yourself.

 

[Lionel Albert]

So if it has got a loop (send / return) it can work like a kind of cabinet ?

I don't have the hardware to try it myself. All I'm going by is the block diagrams.

The block diagrams for the Rumble 100/200/500 and the Bassman 100T/500 hybrid/Super show them to be wired identically at the effects loop. The only difference is the the Bassman series explicitly says in the manual that the effects loop can be used to slave amps and even go so far as to label the effects loops PREMAP OUT and POWER AMP IN.

In my opinion, the "best" way to swing this type of setup would be a preamp/ DI with two outs running directly to each amp.

Work like a POWERED cabinet. That is an import distinction.

But I'm hearing that, for some reason which is not clear, this does not work on the Rumbles. I can only guess that something is left out of the block diagram. Connecting multiple Rumble amps certainly is not mentioned in the manuals.

It absolutely works for the fully-featured, more expensive Bassman series of amps.

Nothing is clear for me, the manual is very basic.

I was working with v3 manuals which have block diagrams.

 

[DerekW]

Isn't just as simple as effects send from your main amp, Ito effects return of the slave amp? Or am I missing a point somewhere here?

 

[Scott Truesdell]

If I understand you correctly, the problem with that is having to make tone or volume adjustments to both amps. Most of the time identically. What a pain!

Have you tried that? I'm pretty sure I remember those that did with negative results. I for one have not.

This is why you go Rumble 500 head with a pair of Rumble 410 cabinets.

Hum, something lets me guess it is not possible...
