[. . . ] Channel A/B: Switches between the Normal and Overdrive channels. When in the "B" (In) position, the switch activates "Channel B" (Overdrive). "A" (Out) position activates "Channel A" (Clean). In order to use the footswitch to control the channel switching, "Channel A/B" should be in the "A" (Out) position on the 2001RB. CHANNEL B: Channel B LED: LED turns on when in the "Channel B" (Overdrive) mode. Gain: Controls the amount of overdrive in the "B" channel. At low settings it provides a smooth distorted sound. At high levels it will provide full saturation with long sustain. Edge: Treble control for the Overdrive channel. B o t t o m: Bass control for the Overdrive channel. Level-B: Adjusts the output level of the Overdrive channel. CHANNEL A: Channel A LED: LED turns on when in the "Channel A" (Clean)mode. Level-A: Sets preamp gain after the input stage. It is used in conjunction with the input pad, to optimize the amplifier's headroom. 4/5 String Bass: Switching this button to the "ON' position, voices the pre-amp for basses with "B" tuning (5 string bass). Leaving it in the "OUT" position will voice the amp like the 800RB, for a four string bass. Contour: Drops the mid-range frequencies while boosting lows & highs. Presence: This adds edge and definition to higher frequencies. 13 2001RB & 2001RBP ACTIVE EQUALIZATION: 11. Treble: Boost and cut at 7kHz+14dB shelving type. High Mid: Boost and cut at 1 kHz +6dB -10dB, "Q Optimized, " band pass type. Works on lower string harmonics, and effects the punch of your sound. Low Mid: Boost and cut at 250Hz +6dB -10dB, "Q Optimized, " band pass type. [. . . ] The way a Bass amp deals with the instrument low string is a critical part of it's sound. In fact, a five string instrument requires an entirely different low end response than a four string instrument. No equalizer can make the necessary adjustments to accommodate both, however the String Bass button on the 2001RB does just that. When it is out, the 2001RB is voiced like the 800RB. [. . . ]
