Hello,

What you are trying to do is only possible using Insert routing mode. When the H90 is in Dual mode, we do not have access to inserts, so you would have to place the drive board either before the H90 or after the H90. With Insert routing mode, you can use one insert for your drive board and the other insert for the FX loop of the amp. The only danger here is you must always maintain the loop to your amp active. Otherwise, you run the risk of breaking the signal chain. This diagram shows you how to connect your amp’s FX loop to the insert. You’re free to connect your drive board to the other insert. The cool thing is you can change the order of everything – algorithms or inserts – on a Program basis.
