Hello to everyone,

I have a Mono In —- Stereo Out pedal ( boss sy-300) too

So, what is the best way to set the H90 Inserts?

My guitar to H90 Input 1

H90 Output 1 to my guitar amp

H90 Output 3 to Boss SY 300 Input

Boss SY 300 Output to H90 Input 3

Is this correct?

If I understand correctly I cannot use a Stereo In > Mono Out H90 inserts, right?

Thanks
