I posted a NAD about my Kemper Profiler the other day and a couple of people asked for a report on how it worked live, so here you go.. It worked - that's the first thing to say! I've always liked the idea of the practicality and versatility of digital for playing live but my experience of it has not lived up to my expectations. Have owned Line 6 stuff, which was very poor live, Yamaha DG100 amp, which was a great sounding amp but always felt very un-natural in terms of response, and have used most of the other usual suspects with mixed results. The Kemper was streets ahead of all of them. Not only did it sound right but it felt right too, which is a huge thing live. I ran it straight into the desk and just used the stage monitors, and it worked really well. My band mates were very impressed, including our rhythm guitarist who has a pathological hatred of digital amps but had to concede that the Kemper was a different league. A few observations. It does take some fiddling to get right, and there's still work to do to get the settings right for live. The pre-loaded profiles are ok, but the commercial ones I bought from The Amp Factory were much better. I set them up at home using a keyboard amp as a monitor, then before the gig took them to my friend's home studio to work with him, as he is a very good sound engineer. When it came to playing live I noticed a few things - the settings that worked in the studio still need tweaking for live use. The reverb is much more pronounced at high volume, and a couple of the settings were much louder than others when run through a full PA. I'll need to tweak a bit more over the next couple of gigs to get everything right, but overall I was very, very impressed with how it worked. When I was in my friend's studio we also had a go at profiling his Blues Junior - we didn't spend a lot of time on it, but the results we got were very good. I wouldn't say they sounded exactly alike, but enough that no-one would notice without carefull A/B-ing, and I'm sure if we'd spent some time tweaking we would have got it even closer. Very impressive bit of kit, and the first digital gizmo that lives up to what I always hoped they would.
