Hi @tbskoglund. I have a similar query on this. My setup is with a Kemper Player and the H90 with the following connections:
Guitar into H90 input 1 > Output 1 into Kemper > L& R out of Kemper into inputs 3 & 4 of H90 > Outputs 3 & 4 of H90 to Pinstripe IDISO+ > FOH
What I am unsure about is if I should setup the H90 with a single insert (1) and position this between A & B blocks or should insert 1 be before block A and insert 2 be between blocks A & B, or after or should it be set up as a stereo insert sitting between blocks A & B.
