I don't think in this particular case (spring reverb) we need to provide any real world examples or added details.
The history of music and amps making use of beautiful spring reverb speaks for itself. If any of us have to explain this, then there is something else going wrong.
The Profiler is a great piece of gear, we all know that. But it will remain incomplete as long as there is no proper spring reverb. Even my post is pretty much unnecessary / obsolete. Just do a spring reverb. Imho this was even more necessary from day #1 than any of the distortion stomps. The spring reverb is an essential (integral) part of many guitar amps. And a few years into the history of Kemper Profiler we still can't do it and still have to discuss this requirement?
I mean, seriously, what piece of information is missing to convince you of the fact that a spring reverb isn't just some wish but a requirement if you want to seriously claim close to perfect amp sound?
Sorry but I had to vent a bit about this sad and long standing topic.
