no, this is completely wrong.
it sees the full output of the amp (post power output and transformer section)
As I said in my *EDIT*...I see that you CAN use it in-between the amp and speakers....however, that's the only way you will get the "full output" of the amp.
If you just use the Line Out found on some amps...chances are pretty good you are only getting the preamp section output and not also the power amp section.
They even kinda say that on the Palmer web page:
"It can be used with line level preamps…."
I don't know how you use it or which amps you use it with...but if it is from the Line Out on your amps...check the manual and see where the Line Out gets its signal from on your amps.
Same thing with most FX Loops...they usually get the signal from the preamp section.
Either way....it looks like a useful device if it meets your needs.
