Last week I purchased a Firehawk. I'm trying to run the 4-cable method, but I'm having some trouble. When my amp (a Carvin V3M) is on the clean channel, everything is fine, and I can use amp sims, etc. But when I switch to my crunch channel on the amp and choose "No Amp" on the Firehawk, I get more noise and very little distortion. I thought it might be my effects loop, but when I run a single delay pedal through it and put my amp on crunch, everything works fine. I've tried moving things around on the Firehawk, but nothing seems to help. Can anyone help? Thanks in advance.
