Add an FX Loop block after the preamp - drag the reverb, delay and EQ down into a separate "loop" path and then put the IR onto the main path as the last block. I'll take some photos of patches I've made and post them tonight for a visual reference for you.

I would suggest a different block setup - treat it like a real rig. Your pic shows the reverb and delay after the IR block. The following is a template I use and then I switch out the preamps and IR's for different tones. Vol>Wah>OD>NS>Preamp>(FX LOOP: Delay, Reverb, EQ)>IR. The order of blocks will have an affect on the overall sound. I'm not familiar with the OwnHammer IR's - I've been using Sigma Audio. They provide 5 mic placements for the IR's and the mic placements do have a huge impact on the tone as well. You'll also want to put a high and low pass filter on the IR's - I set the lows at 80KHZ and the Highs at 8000Khz. Don't give up yet - it takes some experimentation!

I would like to see the OD3 and OD4 channel Marshall JVM preamps in the next update. This has been a fantastic amp for me in reality and would love a version of it on the Helix.
