How to combine the Drive and Deep outputs on the SansAmp Geddy Lee DI-2112 preamp.
It turns out it's a simple push button switch accessible from inside the battery cover. This combines (mixes) both channels together - the combined signal is out of ALL the outputs at the same time. Doesn't matter if you plug into the Drive or the Deep, XLR, or 1/4" = same signal.
