Kemper Releases Free OS 12.0

Kemper Releases Free OS 12.0

Featuring vintage tremolos, modern slicer effects, and stereo auto-panners, the update includes clever Rate and Tempo controls for seamless syncing and morphing.


Today Kemper announces the immediate availability PROFILER OS 12.0 including the highly anticipated collection of advanced Tremolo and Slicer FX for the entire range of KEMPER PROFILER guitar amps.

The Collection features three vintage tremolos, two modern slicer effects, and two stereo auto-panners, that have been derived from the slicer effects. They all feature a clever Rate and Tempo control system, that allows for syncing the tremolo to the song tempo, retriggering the timing by simply hitting the TAP switch, and changing or morphing the tremolo rate to different note values,

The new Advanced Tremolo Modules in Detail

  • The Tube Bias Tremolo is the familiar Tremolo in the Kemper Profilers. Formally named "Tremolo“ and available in the PROFILERs since day one, it is a reproduction of the famous Fender Amp tremolos from the 50‘s. Placed in front of the amp it beautifully interacts with the amp distortion.
  • The Photocell Tremolo dates back to the 60‘s and features a steeper pulse slope, and its width varies with the intensity.
  • The Harmonic Tremolo also dates back to the 60‘s and was introduced by Fender. The low and high frequencies alternate with the tremolo rate.
  • The Pulse Slicer is a modern slizer or stutter effect that will continuously transition from the smoothest sine wave to the sharpest square wave, using the "Edge“ parameter. The "Skew“ parameter changes the timing of the high level versus the low level, sometimes also called pulse width or duty cycle.
  • The Saw Slicer creates a ramp like a saw wave. The saw wave has a falling ramp when "Edge“ is at full position, and a rising edge at zero position. Towards the middle position a rising and falling ramp are forming a triangle wave. The „Skew“ parameter changes the slope of the rising and falling ramp from a linear trajectory to a more convex or concave shape.
  • The Pulse Autopanner and the Saw Autopanner are derivates from their respective Slicers, they spread their signals in the stereo panorama. The "Stereo“-control parameter is included in many effects of the PROFILER. Here, it introduces a novel "super-stereo" effect that lets the Autopanner send the signal well outside the regular stereo image. This effect works best if you are well positioned in the correct stereo triangle of your speakers. When you move the “Stereo” soft knob beyond the +/-100% setting, the super-stereo effect comes into place, reaching its maximum impact at +/-200%.
  • A single press on the TAP button at the beginning of the bar will bring the rhythmic modulation effects, such as Tremolo or Slicer, back into sync with the music without changing the tempo. The sync will happen smoothly and almost unnoticeable, which is a unique feature. Of course, tapping the tempo is possible as well.
  • Modulation Rate - The “Rate” control available in many modulation effects is based on a special philosophy that allows continuous control over the speed of the modulation and continuous Morphing, even when linked to the current tempo via the To Tempo option. The fine Rate resolution shines when seamlessly morphing from, e.g., 1/8 notes to 1/16 notes or triplets without a glitch and without losing the timing of the music.
The "Slice, Wobble, and Dice!“ Update OS 12.0 is a free download for all owners of a KEMPER PROFILER guitar amp

Legendary bassist John Patitucci continues to explore the sound of a chord-less trio that balances melodicism with boundless harmonic freedom—and shares lessons he learned from his mentors Chick Corea and Wayne Shorter.

In 1959, Miles Davis’ Kind of Blue and John Coltrane’s Giant Stepstwo of the most influential albums in jazz history—were recorded. It’s somewhat poetic that four-time Grammy-winning jazz bass icon John Patitucci was born that same year. In addition to a storied career as a bandleader, Patitucci cemented his legacy through his lengthy association with two giants of jazz: keyboardist Chick Corea, with whom Patitucci enjoyed a 10-year tenure as an original member of his Elektric and Akoustic bands, and saxophonist Wayne Shorter’s quartet, of which he was a core member for 20 years. Patitucci has also worked with a who’s who of jazz elites like Herbie Hancock, McCoy Tyner, Dizzy Gillespie, and Michael Brecker.

In our third installment with Santa Cruz Guitar Company founder Richard Hoover, the master luthier shows PG's John Bohlinger how his team of builders assemble and construct guitars like a chef preparing food pairings. Hoover explains that the finer details like binding, headstock size and shape, internal bracing, and adhesives are critical players in shaping an instrument's sound. Finally, Richard explains how SCGC uses every inch of wood for making acoustic guitars or outside ventures like surfboards and art.

We know Horsegirl as a band of musicians, but their friendships will always come before the music. From left to right: Nora Cheng, drummer Gigi Reece, and Penelope Lowenstein.

The Chicago-via-New York trio of best friends reinterpret the best bits of college-rock and ’90s indie on their new record, Phonetics On and On.

Horsegirl guitarists Nora Cheng and Penelope Lowenstein are back in their hometown of Chicago during winter break from New York University, where they share an apartment with drummer Gigi Reece. They’re both in the middle of writing papers. Cheng is working on one about Buckminster Fuller for a city planning class, and Lowenstein is untangling Austrian writer Ingeborg Bachmann’s short story, “Three Paths to the Lake.”
