Thanks, I added a filter block to the CA3+ preset (i added to a new row because it was full so I think I've just bypassed the compressor with lines going around it. Anyhow I right-click the yellow circle below "level" in the filter block (In Axe-Edit) and an edit modifier window pops up. I change Source to Pedal 1 and dial volume knob on pedal to maximize range on graph, but it doesn't seem to do much, I mean in terms of gain adjustment...
