Using a looper stomp box

nomaditerranean

Hello Group,

Please advise whether this connection scenario will work.

Spark 40 headphone output becomes input for looper stomp box.

Output from looper stomp box becomes aux input for Spark 40 (level is controlled by "Music Volume" knob).

Two questions then:

Will it work in theory?
What additional controls/sefeguards/equipment is required to make it work in practice without causing damage?

Many thanks and all the best from the UK.
