Tiny Terror Guitar Head through a bass combo

I wouldn't try it... I'd get rid of the Rumble in the first place.

Sell both the Orange 12" and the Rumble, and get an orange bass cab, and you're set.

 

Not ridiculous.

You're playing an electric guitar through the Orange head and out a Fender Rumble combo speaker (I assume the Fender head is off, and you're just using the speaker)?

That will probably be fine, although you never know what it will sound like. I play my electric guitar through a Streamliner and a Bag End S15 cab sometimes, and I think it sounds great.

 

All good so long as you can disconnect the Rumble amp completely.

 

Don't plug your Terror into the amp part of the Rumble.

What so bad about "lugging" around a 1x12? Are you on foot or something? The Terror will obviously sound way better through a V30 or whatever those are loaded with than a Rumble's bass speaker.

 

It won't damage it as long as you don't us the Rumbles amp section.

As far as a bass cab and speaker for guitar, it might sound deeper, but you might like it as well.

I used to get double duty from a Fender 2x15 bass cab. It was part of a bass rig and I also used it for a few things being driven by a Fender DeVille amp. It sounded thick and sweet and I got a lot of compliments, but the tone would not work for all kinds of music.

 

What they're saying is, you can use the Orange amp, and the SPEAKER from the Rumble combo, but you'll need to modify the Rumble so you can connect directly to the speaker. There is no connection for an amp directly to the speaker as it is now, so you'll need to disconnect the speaker in the Rumble combo, and add a spkr jack that you can connect to. Don't connect the Orange amp into any of the Rumbles inputs, until you ADD a new spkr input.
