Looking at some of the Mesa amp schematics, there is the 'feature' of a slave output and a variable pot to control it's level.
Some amps (eg. Nomad), the Slave comes off an internal winding of the output transformer, and is not part of the NFB loop, so this would not apply to those amps.
On *some* of them (ie, the Heartbreaker), the Slave signal comes off the NFB loop, and has a resistor and pot in series with whatever theoretical load is plugged into the jack. The design likely presumes a high impedance load like a PA input or something like that.
However, if a very very low impedance load (or zero=shorting plug) is placed into the slave jack, a voltage (current) dividing circuit of similar magnitude to the NFB is created, and the slave output potentiometer then becomes a variable NFB control of sorts that should be able to reduce the negative feedback a great deal more than even what the bold switch accomplishes.
Cool?
Thoughts? Risks?
Can any amp techs on this forum validate this idea?
