I've owned my Kemper for a little over a year now and my justification for getting one is that i will never need to buy another amp ever again, maybe a handful of profiles but not actual tube amps.
This may sound like a completely insane position for some people who love tubes amps and i fully understand why, but before i bought the Kemper id played less than 10 real tube amps and so i didn't really have a reference point as to how a real tube amp should behave and sound, i spent at least the 10 months prior to me buying my Kemper researching and listening to reviews of various competitors of the Kemper (Helix, Bias, AxeFX etc...) and saw all the comments from people with real experience praising the Kemper and so eventually pulled the trigger on it!
I found a few stock profiles that i liked and a few from TAF bundle that i got with the Kemper as i bought it from Andertons in the UK who work with Andy so i got a bundle chucked in, but i recently bought the EVH pack from TopJimi and they blew me away! for the music i play they absolutely slay!
