Line Out Clarification

For the Ceriatone Lightning as an example, there is a Line Out jack attached to the 8-ohm lead of the impedance switch. With the addition of 3.3K and 22K resistors to the jack, it can be supposedly be used for recording, output to a PA, yadayadayada...

My quesiton would be, does this stilll require a speaker load plugged into the output jacks, or can the line out serve as the load (without using a speaker) for such purposes without resulting in a fiery amp death?

No. You still need a speaker connected. The line-out is too high an impedance, almost an open circuit as far as the OT sees it.

You could run the speaker out into a resistive load if you want perfect silence. I've done it with smaller amps (record the line out, use a plug-in for cab sim), but you lose the interaction between the amp and the speakers... unless you can build or buy a reactive load.

But the short answer is no.

Short and to the point works, thanks!
