Sound Pure's Take
Engineered for versatile analog drive and filter-shaping, the Genzler 4 on the Floor Classic Bass Overdrive delivers dynamic tube-inspired drive topologies in a compact pedal chassis. Weighing 1.1 lbs (0.5 kg) with physical dimensions of 5" W x 4.1" D x 2.3" H, its drive section features dedicated overdrive engine high-pass (30 Hz – 200 Hz) and low-pass (1 kHz – 14 kHz) filters for tailored frequency contouring. Audio specifications list an input impedance greater than 1M ohm, a 1k ohm output impedance, and selectable nominal input sensitivity (-20 dBu high / -10 dBu low). Dynamic headroom scales with supply voltage, achieving maximum input levels up to +10 dBu (high sensitivity) or +18 dBu (low sensitivity) at 18V with DRIVE at 9:00, while maximum output level reaches up to +20 dBu at 18V (+9 dBu at 9V, +14 dBu at 12V). Power requirements call for a 9VDC–18VDC low-noise power supply with auto-detecting polarity at a 40mA maximum current draw.
From Genzler Amplification
The 4 ON THE FLOOR™ Classic Bass Overdrive is an ALL ANALOG bass overdrive pedal that gracefully emulates 4 different overdrive types found in classic tube circuit topologies and then gives the player additional control over drive/gain, overdrive path (only) with high pass and low pass filters and separately a clean blend. The result is the ability to tailor and fine tune the overdrive to fit with a wide spectrum of music and playing techniques, without the loss of touch sensitivity, musicality, or the addition of induced excess noise. This versatile pedal can be used as a clean boost, an “always on” tonal enhancement, or offering varied overdrive textures to shift through, for selected performance requirements.
Drive Select “Gear” Descriptions:
1st GEAR: Reminiscent of a tube amp’s clean channel (including natural harmonics) with a bit of overdriven tone when driven hard. A nice “always-on” selection.
2nd GEAR: Emulates a tube amp’s mildly overdriven tone, with a small amount of dynamically compliant clipping asymmetry. This is a natural feeling, touch sensitive algorithm with very mild compression that responds with more texture and complexity, the harder you dig in.
3rd GEAR: A more aggressive up-shift from 2nd gear, this moderate, asymmetrical overdrive is less compliant, with greater compression for a tighter feel.
4th GEAR: This is the most aggressive gear of all — a heavier, symmetrical, low compliance overdrive that can enter distortion territory when driven hard. While there are a lot of harmonics and compression present, this gear does not give up tone or feel.
With the versatility in overdrive algorithms and tonal options, the 4-OTF-PEDAL is an excellent compliment to either of our MAGELLAN 350 or MAGELLAN 800 bass amps.
