Kemper has released version 2.0 firmware for the Profiling Amps. Version 2 is a major update, adding a collection of new polyphonic pitch shifting effects, including a real-time formant shifter optimized for guitar, to compensate for undesirable artifacts, such as the “chipmunk” effect. Also included is “Pure Tuning” or “just” tuning for perfectly in tune chords. Other new features include tuner activation when the volume control pedal is set to zero, Performance mode, with 125 performances, each with up to five rigs — ideal for storing the sounds dedicated to the sections of a particular song (intro, verse, chorus, bridge, outro). Version 2 also includes custom foot controller support, and a brand-new set of presets, Rig Pack 04, Keith Merrow Signature Rigs, and Amp Factory Rig Pack.
