Hi, I'm John. I've used a rackmount KPA over the last few years, I just never actually took the time to stop by and say hello on the forum until now. In any case, yeah I've used the Kemper for recording and reamping guitars and bass, and I'm a fan of the unit. In fact, I've used it pretty heavily in some music that I wrote, recorded, and finally released not too long ago. Here is a sampler of some of my work: https://www.youtube.com/watch?v=i7Vv7CrCH-o https://www.youtube.com/watch?v=i7Vv7CrCH-o&list=UUdd2pZ3NYg5eCE9Xu34ty0g&index=2 For what it's worth, my work is available through: Spotify: https://goo.gl/PdPVYh [URL:https://www.youtube.com/redirect?q=https%3A%2F%2Fgoo.gl%2FPdPVYh&v=i7Vv7CrCH-o&event=video_description&redir_token=3yVU5TM-r2xfxry0geLR7BrR-DV8MTUzNjQ1ODE1N0AxNTM2MzcxNzU3] Bandcamp: https://deathbenotproud.bandcamp.com/ [URL:https://www.youtube.com/redirect?q=https%3A%2F%2Fdeathbenotproud.bandcamp.com%2F&v=i7Vv7CrCH-o&event=video_description&redir_token=3yVU5TM-r2xfxry0geLR7BrR-DV8MTUzNjQ1ODE1N0AxNTM2MzcxNzU3] iTunes, GooglePlay, et al: https://goo.gl/U1gQ34 [URL:https://www.youtube.com/redirect?q=https%3A%2F%2Fgoo.gl%2FU1gQ34&v=i7Vv7CrCH-o&event=video_description&redir_token=3yVU5TM-r2xfxry0geLR7BrR-DV8MTUzNjQ1ODE1N0AxNTM2MzcxNzU3] -John
