Hammond B-3 vs Clonewheels
A clonewheel organ emulates the electromechanical Hammond with solid-state or DSP/computer-chip circuitry instead of mechanical tonewheels — trading the B-3's weight and fragility for portability and reliability.^[raw/articles/wikipedia-clonewheel-organ.md]

Dimensions of comparison
| Dimension | Hammond B-3 (1954–75) | Korg CX-3 (1979 analog / 2001 digital) | Roland VK-7 (1997) | Nord C1/C2/C2D (2007–) | Hammond-Suzuki XK-3/XK-3c (2004/08) & New B-3 (2002) |
|---|---|---|---|---|---|
| Sound source | 91 real tonewheels, tube preamp, key-click contacts | 1979: analog circuitry; 2001: REMS physical modeling | "Virtual Tonewheel" DSP ^[raw/articles/wikipedia-hammond-organ.md] | Physical modeling + samples; C2D adds 2×9 real drawbars/manual | Digital tonewheel modeling from the B-3's own brand ^[raw/articles/wikipedia-hammond-organ.md] |
| Weight | ~425 lb with bench + pedalboard ^[raw/articles/wikipedia-clonewheel-organ.md] | ~37.5 lb (17 kg, 2001 model) | Portable combo format | Portable dual-manual | Modular: single manual + optional lower manual/pedals ^[raw/articles/wikipedia-hammond-organ.md] |
| Drawbars | 9 real drawbars per manual | 9 (1979) or 2×9 (2001) | Yes, sliding | C1/C2: LED "drawbuttons"; C2D: real drawbars | Real drawbars |
| Leslie | Real Leslie 122/147 (11-pin / 6-pin) | Built-in rotary sim; 1979 unit favored through a real Leslie | Simulated | Simulated or real Leslie via 11-pin jack | Often paired with real/current Leslies; full-size New B-3 can exceed $10,000 ^[raw/articles/wikipedia-clonewheel-organ.md] |
| Extras the B-3 lacks | — | EX mode synth voices (2001), 128 presets, MIDI, reverb | MIDI, presets | Also emulates Vox and Farfisa (C1/C2), plus pipe organ (C2); delay/reverb | MIDI/preset flexibility, lightweight modules (XB/XM series) ^[raw/articles/wikipedia-clonewheel-organ.md] |
| What it can't fully copy | The original's complex interplay: tonewheel leakage/crosstalk, aging, dirty contacts, real rotating Doppler | Keyboard's Keyboard review "Clonewheel Heaven" (2004) found some vintage aspects unreproduced ^[raw/articles/wikipedia-clonewheel-organ.md] | Same modeling limits | Emulation, not mechanism | Keyboard feel: Larry Goldings — every company including Hammond itself has tried to duplicate the patented key mechanism; none quite have, though "Hammond has gotten pretty close" ^[raw/articles/npr-blogsupreme-hammond-b3.md] |
Verdict / synthesis
The generations matter. First-wave clones (Roland VK-1/9, early combo attempts) were criticized for unrealistic upper harmonics and rotary simulation, and jazz/blues players kept vintage Hammonds for recordings ^[raw/articles/wikipedia-clonewheel-organ.md]. The Korg CX-3 (1979) was the first lightweight organ with genuinely comparable sound — Gordon Reid called it close to "the true depth and passion of a vintage Hammond," especially through a real Leslie ^[raw/articles/wikipedia-clonewheel-organ.md]. By the 1990s–2000s, DSP modeling and sampling closed most of the audible gap: leakage, key click, tube growl and Leslie rotation are now explicitly simulated, and educated listeners can be fooled "especially if it's still going through a Leslie" (Goldings) ^[raw/articles/npr-blogsupreme-hammond-b3.md].
The practical trade is decisive: clonewheels dominate touring and club work (weight, reliability, cost), while vintage B-3s retain prestige and a following for studio and gospel/jazz work, where the wooden instrument's look, springy patented key feel, and unpredictable vintage character are part of the music. Goldings also notes that vintage Hammonds vary from unit to unit like pianos — a variability clones deliberately normalize. The remaining honest gap is haptic (the keyboard action) and the physical Leslie, not the tone generation. ^[raw/articles/npr-blogsupreme-hammond-b3.md] ^[raw/articles/wikipedia-clonewheel-organ.md]
