Manufacturer's Description from Genzler

GENZLER™ AMPLIFICATION is proud to announce the introduction of our first bass instrument amplifier, the MAGELLAN™ 800. 

Inspired by the courage and spirit of exploration, the MAGELLAN™ 800 represents the pinnacle in the next generation in lightweight, high-output, versatile, bass amplification.  With our years of research, design and manufacturing expertise, we’ve developed this model utilizing stringent design parameters for form, function, fit and finish.  The result is an 800-watt professional high-powered tour-class bass guitar amplifier weighing only 6.25 lbs! 

This is exactly what players have come to expect from the GENZLER™ design team -- performance, versatility, and reliability.  From natural, pristine, transparent reproduction of the bass instrument to classic, vintage harmonic textures with “weighted feel to the notes”, the MG-800 provides the tonal pallet needed to cover all of the bassist’s amplifier requirements. 

The expanded feature set and output power level make this amplifier an essential tool on the global stage, and with its universal power supply, the MAGELLAN™ 800 can be used with any voltage around the world without modification.

About Manufacturer

The next generation of Jeff Genzler-designed products is as smart, pure, and innovative as the originals. Genzler Amplification is now an independent, Brooklyn-based family business with a legacy of exceptional service and uncompromising quality.

This is the product you expect from the people you trust.



PREAMP – dual channel, all solid state analog design with integrated soft clip circuitry.

INPUT– 1Meg ohm input impedance

INPUT PAD SWITCH – attenuation of -8.5dB

CLEAN CHANNEL OVERVIEW – Voiced to provide natural, pristine, transparent reproduction of the bass instrument.

DRIVE CHANNEL OVERVIEW – Voiced to provide a more “driven” tonal signature and harmonic content along with a softer top end and more relaxed low-frequency response.

CONTOUR -- continuously variable control of 2 vastly different response curves. In either CURVE position, when the SHAPE control is all the way off (CCW) the response curve is completely FLAT.

Curve A (Blue) -- a variable pre-shaped curve that boosts lows and highs while simultaneously cutting mids.  The slopes are fairly gentle which keep the tone shaping very musical.  This curve covers a wide range of sounds from flat to classic to modern depending on the position of the SHAPE control.

Curve B (Amber) -- a variable pre-shaped curve with attenuated high mids and highs, a low mid bump, and a slight roll-off of the lowest bass frequencies. Again, the slopes are fairly gentle which keep the tone shaping very musical. This curve is intended to provide sounds in the range of vintage amps and vintage cabinets that do not have tweeters. 

ACTIVE EQUALIZATION – The MAGELLAN™ 800 contains an active 3 band equalizer with a sweepable parametric mid-range frequency control.

Bass   +/- 15dB boost/cut shelving curve with a corner frequency of 75Hz

Mid      +/- 15dB boost/cut of the variable mid frequency selected

Freq     Variable mid frequency from 150Hz-3kHz

Treble   +/- 15dB boost/cut shelving curve with a corner frequency of 6kHz 

POWER AMP – The MAGELLAN™ 800 uses a state of the art, class D power amplifier design and a high frequency auto-sensing universal switch-mode power supply (SMPS) to achieve unprecedented high performance and lightweight packaging. There are no Voltage Switches to change or jumpers to move. This SMPS senses the line voltage from 100-240 Volts and automatically configures itself.
