Hi Uber Guru, could you describe a setup with a looper:
1. Record guitar (plugged in in looper, looper in Amplifi, record sound from amplifi on looper).
2. Play back loop (clean on amplifi, line in).
3. Play guitar (still plugged in looper), signal to "guitar in" on amplifi with an an other sound.
Problem: no send/return, headphones out will mute the amp
