I finally got my Firehawk FX and discovered that the 9v cables that attach to my DC brick do not fit. So... it's time to mount the cable under the pedalboard. Also, the 4 cable method into my Mesa Lonestar 2x12 sounds epic. Being a "Tube Guy" my whole career, I was skeptically optimistic to see if the amp sims feel and sound right. I'm very happy to say that the sounds I'm getting are legit. Best money I've spent in a while.
