Now we’re gettin somewhere. That pedal’s a Plexi clone, right? If so, lots of nice mids. Do your amps have separate EQ for each channel? If so, push the mids on the clean channel up. I bet that solves the issue. If not, try kicking on the EQ pedal with the mids pushed when you go to the clean channel. But the simplest path is to use your clean channel for your clean and your dirty channel for dirty, as you mention. Then you are not adding a separate EQ item as well (the Caline pedal) when you go to the dirty channel. Either way, Hope that helps. Rock on!
