The mighty B2000 mono block head has been called the "King" of bass amps for one reason - its massive 2050 watts. Its style offers the classic boutique look that in part comes from the large brass knurled chrome knobs, which offer a solid feeling when using the controls. Featured in a 19" 2U rack mount package weighing under 14 pounds, the days of 80 lbs amps are over. But more then power, it’s the big tone this amp produces from its CLASS A preamp, 6 active EQs and warm 12AX7 tube. The B2000's light weight, premium features, rugged construction, including the exclusive "lock-in" AC cord, offer the bass player what he/she needs to be heard and felt. Nothing provides a better foundation than the B2000 - huge power and big tone. 

High Headroom Tube Driven Power Amp 

The high output B2000 produces 700w RMS at 8 ohms, 1300w at 4 ohms or 2050w at 2 ohms. The B2000 uses three different transparent limiters to maintain its high headroom to assure ultra clean power even with extreme string slapping. For added warmth, take advantage of the internal 12AX7 TUBE that utilizes two stages that precede the power amp section. 

Drive Control 

The DRIVE control adjusts the input level to the CLASS A preamps and compensates for the input sensitivity of various bass pickups. The DRIVE will add harmonic content to your sound when approaching 10 on the dial, which pushes the CLASS A preamps into a sweet overdrive. 

Dedicated Tone Circuits 

Tone begins with a boutique flat response. However, the 6 active tone circuits are available to carve out your signature sound, starting with the SUB BASS. Its simple yet powerful controls make it easy to dial in your idealized tone without fussing with lots of knobs. 

Direct Output 

The direct out features a DI LEVEL control and PRE/POST switch on the rear panel controlling the XLR balanced output on the rear. The PRE setting is buffered directly from the first stages of the preamp to the XLR. The POST setting includes the EQ and EFFECTS LOOP, bypassing the MASTER LEVEL. This enables level changes without affecting the XLR output. The XLR is muted by the MUTE switch. The GROUND LIFT switch next to XLR helps isolate hum to the recording or PA console.
