I am playing guitar 30years. I have several guitars and my amp is a Marshall JVM205C, plus a variety of stomp boxes arranged in a pedal board. I never bothered with multi effects units previously as they either just didn't sound good, where too expensive, and very complicated to use! Then the Amplifi FX100 came along and I got one. It sounded great, and the more I used it the more I thought about how it could be improved, especially for live stage use.
Then, as if by magic, Line6 released the Firehawk. It was as if they had read my mind. It had the extra functionality that I had craved, and a lot more! And with the addition of HD models the range of sounds is even better.
I can use this with my Marshall (in front of the amp on a cleanish channel or straight into the power amp section via the effects loop on the amp) or into an active monitor or PA and the sound is awesome every time. The sounds available straight out of the box are great but being a bit particular I took some time to create my own sounds using the app and then saved them to the pedal board (to use without the need for my tablet every time). It's like having dozens of amps and pedal boards at your feet that you can change with the flick of a button and the ability to switch the stomp boxes on and off with the 5 extra foot switches is the icing on the cake!
Excellent product, excellent value, extremely easy to create sounds with the app, and very easy to use and set up in a live situation. Highly recommended, check it out the many demos on you Tube!
