D.I. box for electric bass guitar that is capable of dialling up big vintage tube tones, bright modern slap sounds, gnarly distortions, and all in between, providing three different outputs to drive power amps, recording desks, PA mixers, or simply enhance user’s current rig. Controls include Presence for definition and upper harmonic content; Blend to combine the proportion of direct signal and SansAmp circuitry; and active EQ specifically tuned for bass with 12dB of cut or boost. With the popularity of 5- and 6-string basses going beyond fad status and becoming mainstream, it also features an added switch to adjust the bass frequency to extend into those lower registers. There is also a mid-range control and a switch to adjust its frequency. The box is phantom power operable, or uses optional DC power supply (Tech 21 Model #DC4-A), or 9V alkaline battery (not included). Dimensions: 121 x 95 x 51 mm. Weight: approx. 400 g.
