200 factory presets and extensive online resources
Right out of the box, the Kemper Profiler Rack has a ton of profiled amps ready to play. Just connect the Profiler Rack to your sound system or recording rig, and you're set. And even if you don't have a collection of amps to profile, there are hundreds of profiled amplifiers available online, and the community of Kemper profilers is growing every day.
Profile your own amplifiers
While the incredibly lifelike profiles included with the Profiler Rack will appeal to everybody, you'll love the Profiler Rack if you have a ton of amps already. It's easy to connect the Profiler Rack to the amp you want to profile, hook up a microphone, capture the sound of that, amp and store it as a preset. You'll be amazed at how accurately your profiled amp preset responds to the gain and tone controls.
The perfect link between stage and studio
Ever been frustrated trying to re-created the tone you captured on a recording when you play out live? Then you'll love the Profiler Rack, because it can profile your studio sound while you're recording. Just take a split of the mic you're recording with and use the split signal to connect to the Profiler Rack. You'll capture the sound of your studio performance, ready to be recalled on any stage in the world at a moment's notice.
