DEMETER BASS AMPLIFICATION

HB-600 Integrated Bass Amplifier

Now you can have the best of both worlds with the famous Demeter HBP-1 H Series Tube Bass Preamplifier in the same chassis with a high quality MOSFET power amplifier. This compact system delivers all the tone and power needed for almost any playing situation.

The preamplifier features a high voltage all-tube front end for the classic Demeter tone with solid state output drivers and parametric EQ that will adapt your tone for any environment. Other features include active buffered effects loop with controls up front, tuner output, mute switch, three band passive tube EQ with presence control, fully balanced outputs both TRS and three pin, pad and ground lift for PA/recording.

A powerful MOSFET power amplifier section with over 400 watts RMS power into 8 ohms (the most "tube-like" sounding of all power amplifiers). Includes a parametric EQ with fully variable EQ and frequency and finally an unbalanced output for extra power amplifiers with unbalanced inputs. As with all of Demeter equipment, it is meticulously hand-wired using only the finest components available and built in the U.S.A.
