Want to use 1x12 extension cab with Roland Cube 60…

[GuitarGuy503]

Hello,

I’m interested in using a 1x12 extension cab with my Roland Cube 60. Having said that, I know the cube has an 8ohm extension cab jack but I read that the combo speaker will also be active when using the extension cab jack which I don’t want (not to mention that there would also be a mismatch of impedance at 4ohms). In conclusion, is it true that I can plug a 1x12 extension cab into the Cube 60’s lineout jack to run just the 1x12 extension cab alone? I have read this and wanted to confirm. Thanks.

No this will not work. LINE OUT is for line-level recording or to go direct to the board. It is not a powered output. You will not be able to bypass the stock speaker without opening up the amp and doing some very minor mods.

Could you go from the line out jack into a poweramp into a speaker?

yeah, or into a little preamp/amp combo like a quilter

Yeah, he could add a switch to disable the combo speaker pretty easily.

Thanks. I have reached out to a local company in regards to this modification. Will let you guys know what they say.

My only consideration, and I might be wrong, is that putting a switch to disconnect the internal speaker might not be enough. If you plug into the EXT speaker and disconnect the main speaker, the amp might still be looking for a load from the main speaker. I would probably go with a switch and an additional AUX jack in the back coming off the main speaker terminals to switch from the speaker to the new additional AUX jack. Like I said I could be wrong, I am not familiar with the power routing of a Cube 60, but if I were to do this mod this is the route I would go.

How about a 3-way for internal speaker, both that and aux in the middle and aux only? I did a similar mod to a Crate V30 in 2005-6

You can just add a jack that will disconnect the internal speaker when you plug another cab in. I did this to my combo, only did it the opposite. (External amp to internal speaker.) You'll need to drill a hole for the jack.

Nice ArtieToo much cleaner and functional
