Wall-blasting power and pro tone with headroom to spare.

The Genz Benz GBE 1200 bass amp takes the excellent design and tonal refinements of the GBE 600 and adds 1200W output power (at 2 ohms). Its ability to drive resistive and reactive speaker loads plus its extended burst power makes it louder, punchier, warmer and more articulate. The GBE 1200 is 3 rack units high with a beautiful 5mm-thick aluminum faceplate and curved metal rack handles. It has a dual channel preamp--one FET and one tube--with 5-band active EQ for maximum tonal flexibility. Each preamp can be used individually or blended together. In addition to the channel controls, it also has Genz Benz's Signal Shape circuit with Low Frequency Extension, Mid Scoop, and High Frequency Attack controls. The channels and Signal Shape circuit are footswitchable with an included 5-button footswitch.

The GBE 1200 delivers 550W at 8 ohms, 1000W at 4 ohms, and 1200W at 2 ohms. It has an active/passive selectable input, signal mute switch, tuner out, a soft-limit circuit, LED indicators, master volume, sturdy metal chassis, knurled aluminum knobs with detents, variable speed fan cooling, full-featured D.I., three effects loops, slave out jack, dual SpeakonĀ® output connectors, POWERFLEX impedance circuit, impedance selector switch, dual voltage switch, and a heavy-duty toroidal transformer. 19"W x 5-1/2"H x 15"D. 42 lbs.

Powerflex impedance circuitry optimizes the massive power supply to more effectively deliver maximum power at 4 ohms and extended 2 ohm operation into reactive loads. A large switch on the rear panel is provided so that the amplifier can be switched to correctly match the total cabinet impedance load. A front-panel amber LED indicator indicates when the Powerflex feature is switched to 2 ohm operation.

Great value on a really solid bass amp!


from Charlotte, NC

Comments about Genz Benz GBE 1200 Bass Amp:

First of all, the construction of the amp is absolutely superb, it just feels solid and the control knobs have a very nice detented feel to them. At first, all the tone shaping ability of this amp appears daunting, but I was able to dial in nice fat/growly tones in a few minutes on both the FET and Tube channels. Overall, it's very flexible with the solid state and tube channels (and the ability to mix them), lots of eq available and the global tone shaping section adds yet another layer of goodness. This amp is a great value.

Simply Amazing


from Wisconsin

Comments about Genz Benz GBE 1200 Bass Amp:

By far the greatest amp I've ever played on. The dual preamp gives unsurpassed flexibility that allows you to mix the warm tone of tubes with the full sound of solid state. Don't buy an Ampeg until you've tried this thing out. The only negative thing I have to say is that for the first 10 minutes, the controls are a little confusing. Otherwise, top notch amp.
