Got my Firehawk yesterday and he are my first impressions after spending a couple of hours with it today, side by side with my current rig (Mesa TA-15 with a bunch of analog pedals). The Firehawk is running direct into an Alto TS110a. I use two base tones with my current rig - a Vox clean and a Marshally crunch tone - everything builds off of those tones. So my first step was to try to match something in the Firehawk to my base tones. No effects - just straight amp models. The Vox was surprisingly easy to pull off - I got about 90% of the way there with with the TB model and mic selection right off the bat. Tweaked the mids a touch with the EQ block and got there. I can't say it's 100%, but it's a very pleasing tone. The Marshall was a bit of a surprise - it turns out I run my "overdriven" side pretty clean and get most of my crunch from my boost pedal . . . so I wound up just trying to get my crunch sound with an amp alone. I got something I like a lot, but not really the same. I'll fiddle with the EG a little and see if I can get closer. Touch sensitivity - check Amp in the room feel - check. I have to say that I'm really impressed. I even ran my acoustic through it with one of the acoustic models and it sounded pretty good (it will need some eq to kill the piezo-iness of my guitar, but the Variax is looking way more attractive). Finally, the app interface (I use an iPad 2) is awesome - truly easy to use with a shallow learning curve (but see below) The negatives: There is a gap when switching tones - it's not problematic for the songs I tried it on because of how the transitions work, but it could be a problem for other songs. I want to move to a digital board so I can quit tap dancing, but the Firehawk really won't do it - the only way to simultaneously turn multiple effects on and off is to switch patches which triggers the gap. The need a "pedal switcher" mode that keeps the amp loaded and lets you switch pedals in and out (and, no, I don't think the HD500 can do this either - on that you can assign multiple pedals to one switch, but you cant assign one pedal to multiple switches, which is what you need to do more than two "effect scenes"). The gap is better when the Bluetooth is off, but it's still there. The Bluetooth connection is really, really flaky. My connection drops constantly and you have kill the app and restart it and then wait for your entire preset list to reload into the app (which takes a couple of minutes) before you can do anything. Very, very, very annoying and could be disastrous if you are trying to changes things on the fly live. Three suggestions: 1) enable a wired mode (USB/Camera Connection kit?); 2) some way to reset the connection from the app (or the device) without having to restart and 3) something faster than a total reload of every preset (maybe store the presets in the app and some kind of table compare to detect changes? There has to be a better way) - it would also allow you to re-organize your presets when you're not hooked up to the Firehawk). I suspect the Bluetooth culprit is the several Bluetooth devices in my office - there's got to be a way to fix this without me having to shut everything down to program my unit . . . . Bottom line - soundwise, I think it's more than adequate for my needs and will probably replace my current rig. I need to play with my band to confirm, but I'm optimistic. It would be a slam dunk with out the negatives (especially the Bluetooth - there's no other way to program the unit, so this is a deal-killer issue).
