I am looking to upgrade from a Line 6 Vetta to a new amp for the purposes of recording and live playing. The amps I am trying to decide between are the Kemper KPA and the Fractal Axe-FX. I realize that these amps have been compared endlessly, but I am looking for recommendations based on specific needs and I am trying to find a way to kill many birds with one stone!! I will say that most of the threads I have read about the comparisons were posted pre-update for both amps, so if there is any new light on the head to head comparison...I would love to hear about it.
1) Recording needs: My band's music is pretty wide in range (Extreme Metal to Ambient/Acoustic) so I am looking for something that can handle aggressive modern metal tones equally as well as sweet warm cleans. I also record the bass guitar for the band and I would like to use the amp as my bass rig as well, if this is possible. We record in a home studio so loud amp/mic'ing is not an option.
2) Live needs: The high gains sounds must be there for the metal band, but I also play in an acoustic duo and I would like to use the amp as my acoustic amp as well (if possible). I have both a piezo and a magnetic pickup in my acoustic guitar with separate inputs so the amp would be run with the "pickup" jack.
3) If I decide to go with the Kemper KPA, I saw a mod that would let me use my Line 6 longboard. Is there any updates to this concept or should I look for a new pedal as well? If it is the new route, which midi pedal is the best fit for the KPA?
4) I would love to have all of the effects in the Axe-Fx at my disposal, but I have read a lot about the KPA being more "natural and "authentic" in tone. Would the Kemper with outboard effect (ie. Eventide pedals) be preferable to the Axe-Fx? Also,would the Axe-Fx effects be good to use as an outboard effects unit for other things besides guitar during mixing?
Thanks for taking the time to read my ridiculously long question!! I look forward to hearing your opinions!!
