Detail 01
Two inputs to one output
The unit sums two signals into one mono signal.

Independent shopping perspective
The Summing Amp brings two incoming signals together at one output as a mono signal. Connect two effects to its marked inputs, then take one output onward in the rig. Its purpose is parallel routing: two delays can remain distinct instead of delaying each other, while overdrives can sit alongside one another rather than pushing each other in series. It can also combine fuzz and compression in parallel, avoiding the compression choking the fuzz.
