I've had the Profiler for a few weeks now and have given it some decent playing and tweaking time. I am currently working on a project recording early 60's instrumental surf, spy, and spaghetti western music, so I am using clean Fender tweed and brownface tones. I purchased the complete package of Tone Junkies profiles and have found some great clean Fender sounds, especially the Bandmaster and Bassman clean profiles. I am really impressed by how realistic the Kemper sounds and feels.
I am also going through a reissue Fender Reverb unit with NOS RCA 6k6, 12AX7 and 12AT7 tubes. Playing with my Fender Jazzman and Jaguar, they really sound authentic.
How much do I like it? I've got my Fender Blues Deluxe Reissue and Marshall 1x12 tube amps up for sale, along with a number of pedals.
