I have a B-52 AT-100 all-tube amplifier head. I currently have it connected to a LINE-6 Spider 412 four-speaker cabinet. In order to really drive the tubes, I have a vintage Scholz Power Soak, which is a bunch of resistors that allow the user to step down the volume output while still running the head at maximum volume.
The setup looks kind of like this:
The quietest setting on the Power Soak is -32Db, which allows for playing at a reasonable volume while still driving the tubes at max power.
While the -32Db setting on the Power Soak is labeled "PHONES," presumably indicating that it's possible to drive headphones instead of a cabinet.
However, it's still really a lot of power output, I still have to turn down the main volume to about 30% in order to play it in my house. Without the Power Soak, it's likely that I'd blow out the windows in a fifteen mile radius.
In interests of space, I'd like to get rid of the cabinet and simply take the output of the Power Soak and route to actual headphones or a recording hub. I'm not really ever playing stadiums, so the cab is a bit overkill. However, I really like the sound of the amp being driven through the Power Soak.
What are my options for getting rid of my cabinet in a way that would allow me to play with headphones? I could always buy another Power Soak and step things down even further, but as I'm trying to reduce physical space as much as possible, is there a better option?
