I also ran two POG type presets in parallel when I first got the H90. After a while I realised that I preferred the 1 Oct up and 1 Oct down only preset and set about making it sound like my great Boss OC5. It’s almost there. When I last compared them there was a touch of “room” in the H90 whereas the OC5 is slightly drier for leads. If you aren’t comparing them the H90 is good enough for me to have removed my OC5 from my board.

I run this in front of my amps preamp stage but I have got usable stacked sounds with either half of the stack in the effect loop or the entire program in the loop but then I found that with the H90 you don’t need to stop at octaves and there are other great intervals to be dialled in with the expression pedal when you want them.
