I just got back from the rehearsal. I played the Kemper through a Marshall 412, and used 4 profiles: a Top Jimmy SL 68, and 3 others that came stock, I think they are from TAF (JCM 800, Matchless and Bassman). It sounded really good, everyone in the band liked the tones. However, I must dig more into the Kemper and to know better about volumes and how to proper set it up. Sounded great, but I think I can do better. I had to increase the Power Amp boost and Master Volume quite a bite to keep up with an Orange TH100 that the other guitar player was using at the studio. But the Kemper sounded great, just like a real Marshall.
So far, no complaints here. There is a lot to do with the unit, but even for a simple plug and play guy like me, it has its value. You don't need a ton of profiles, I see myself using about 5 different amp tones and some fx. Still, the portability, the different tones and the options I get with the Kemper Power Head (cabinets in the rehearsal studio, cabinets live, FOH etc), the value is amazing. In love with the Kemper really.
A question though, for you guys using the KPA with 212 cabinets: are you scared to turn up the volume to keep up with drummers? I am affraid the PPC212 might not hold up so well, and I will have to increase the volume so much that I might blow a speaker up (although there are several posts from people saying this is very difficult to happen - including one from ckemper himself).
Thanks for all the help! Appreciate it so much.
Cheers
