Here’s other users users’ thoughts on looper placement in the signal chain https://travelingguitarist.com/where-to-put-looper-pedal-signal-chain/
User Quad has an interesting thread on signal routing Aeros settings to change location of looper in my signal chain
My takeaways from the answers given here are that
- Conventional wisdom from vendors like Singular Sound and Roland is that loopers should be placed at the end of the signal chain.
- Looper users suggest not being afraid of placing your looper in the effects loop and within other configurations of your signal chain.
There’s enough experience from both camps to provide you with the logic to support whatever placement decision best suits your needs.
