Ampeg B4R / B4-R Bass Guitar Amplifier Head

The Ampeg B4R Bass Guitar Amplifier Head, 1000 Watts, SS Preamp, Stereo Power Amps. One-kilowatt Ampeg bass head.

The Ampeg B4R bass head delivers straight-ahead power and tone so you can rock like a world class act-even before the royalty checks roll in. The 1000-watt B-4R is the most powerful head in its class. Introduced by Ampeg in 1999, this powerhouse head gives you everything you need for today's music. Not only is the B-4R powerful, it's loaded with tone-shaping features like nothing you've ever experienced. The 9-Band Graphic EQ can either be used to custom tailor your sound to the room, or it can be used to set up a "second channel" for your show-stopping bass solo. In addition to the B-4R's five-position Style switch, the Ultra Mid control provides tonal fine-tuning that should satisfy even the most finicky player. And if you want to really push the envelope, just engage the Texture switch to activate Ampeg's patented tube emulation circuitry. The ultimate biamped bass head-the Ampeg B-4R.
