Genzler MG800 Magellan Bass Guitar Amplifier Head (800 Watts)

With enough power to make the largest stages rumble, the MG800 is also loaded with features like an active 3-band EQ and a drive section for a little crunch.

Inspired by the courage and spirit of exploration, the Genzler MG800 Magellan 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 palette 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.

- 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.

I spent several hours plugging in all my basses (some active, some passive, EMG pickups, Seymour Duncan pickups, Bartolini pickups, etc..). Every bass had a voice that came across the Genzler. Each was unique and I was able to hear minute intricate nuances they had to offer. This amp has a commanding voice, not hifi but modern. I would put this amp between the EBS hd350 (best amp ever) and a MarkBass. The drive offers just enough grit that you can actually use. No overkill. Left on flat and using the clean channel is breathtaking. This amp has body yet it breaths. Warmth with clarity and presence. As you tweak the eq and/or A/B contour, you can actually hear the subtle changes in sound and articulation. At present, I cannot see myself using another amp. It’s if I have arrived at the holy grail of amps. Let’s face it, many times you have amps with too much of their own color (nasally, booming, muddy, clean/sterile). Like I started before, this amp has both warmth and clarity that allows for your voice to color and change the mood.Rating for Manufacturer Support only 1 because I have had no need to call for service or help.
