Amp Slaving: Aux speaker out to Boss Waza Tube amp expander, line out to Slave head.

[ShredmasterAFG]

Hi everyone, this is my first post, so please forgive me if I am the dumb.

I am the kind of person that thinks of wild stuff. My current goose chase is to find out whether or not it is possible to use a load box to slave a slave amp to another amp that does not have a slave out. My dream is to use a Bartel Roseland into the Boss Waza Tube Amp Expander and then on to one of those 80's Slave power amps and on to a cabinet.

So, my questions are,

1. What level does a slave amp generally need at the audio input jack.

2. Is this line of instruments possible.

3. Is there some simpler way that I'm ignorant of.

Thank you for your time.

1) Do you plan to also use the Bartel speaker/amp, or do you want it muted.
2) What is the slave amp? Does it have instrument level inputs or line level inputs?
