Hammond XK-4

Description

Essential Information About the Hammond XK-4 Portable Organ

  • MTW2 Engine: detailed modeling of the 91 tonewheels to capture the dynamics and character of a "B-3".
  • Immediate Control: readable color screen, traditional drawbars, and assignable controls for real-time sound shaping.
  • Next-Generation Digital Leslie: 8 iconic models (including 122, 145, 147) with advanced settings (speeds, ramps, microphones).
  • Vintage Warmth: tube and matching transformer modeling for a denser, fuller sound ready for the stage.

A Modern Heir in the Hammond Lineage

The Hammond XK-4 stands as a modern synthesis of the Hammond spirit: a portable instrument designed for keyboardists who want the authenticity of a tonewheel organ without sacrificing editing comfort and the reliability of a stage keyboard. With its Modelled Tone Wheel 2 engine, it does not merely imitate a timbre: it reproduces the life, nuances, and behavior, while expanding the palette with transistor "combo" organ models (Italian, British, Japanese) and customizable classical and theater organ banks.

Keyboard Design

The XK-4 features a light-touch organ keyboard with virtual "multi-contact", designed to replicate the fast response and characteristic feel of historic Hammonds. The drawbars allow instant harmonic blending, while the programmable pitch bend and modulation wheels add contemporary expressiveness for studio and live contexts. The beech wood side panels complete an aesthetic faithful to the brand's DNA, blending tradition and performance instrument.

Sound Quality

Sound generation relies on MTW2 modeling, with precise work on the 91 tonewheels to achieve an organic, rich, and responsive sound. The digital Leslie aims for an immersive experience by modeling movement, speeds, and transitions, with fine control over ramps and mic placement to tailor the stereo image to your amp or front of house. To recapture the character of legendary machines, the XK-4 also includes tube modeling and an emulated matching transformer: enough to thicken the attack, enhance presence, and provide that "vintage" relief that makes a difference in a mix.

Built-in Effects

  • Hammond Chorus/Vibrato (three generations) and Touch-Response Percussion
  • Overdrive: Tube, Solid, Clip, EP Amp
  • Multi-effects 1: Tremolo, Wah, Ring Modulator, Compressor
  • Multi-effects 2: Phaser, Flanger, Chorus, Delay, Auto Pan
  • Leslie: 8 models (including 122, 145, 147) with independent volume, Fast/Slow speeds, ramps, and mic placement
  • Master EQ to adjust tonal balance according to room, amp, or PA system

Educational Features

The highly readable color screen and direct interface facilitate ease of use: parameter editing, sound memory, and quick access to essential settings. For practice at any time, the headphone output allows silent playing, and the AUX IN input with dedicated volume is ideal for playing along with tracks, playbacks, or external accompaniment while maintaining level control.

Advanced Features

Designed for the stage, the XK-4 relies on assignable buttons and switches to control internal functions according to your preferences. Connectivity covers professional needs with LINE OUT L/R, ROTARY OUT, and ORGAN PEDAL OUT, as well as an 11-pin Leslie socket (with automatic digital Leslie deactivation when a Leslie speaker is connected) and a dedicated input for the optional Leslie "Half Moon" CU-1 switch. For integration, USB A/B ports serve for USB drive backup and direct PC/Mac MIDI connection, and the instrument remains compatible with Hammond MIDI pedals XPK-130G, XPK-200GL, and SK25 for a full organ playing experience.
