For most players, when you are using an effects pedal like the Firehawk FX, or real stomp boxes, you will be setting your amp on straight CLEAN... If you want 2 reverbs, you can run the reverb on your amp as a master, overall reverb, and use additional reverb on your Firehawk patches... My cousin uses a Marshall and sets it to CLEAN and lets his POD Live XT make the tones and do all the work... I do the same with mine, with some reverb on the straight CLEAN amp.
I have 3 different amps, so depending on the size of the gig, I set them all to CLEAN with a bit of reverb, then I use the Firehawk for my patches. That way, it doesn't matter what amp I use, I always have the tones I want on any amp I use...
