The DE1200HD was designed for the bass player who needs great tone, stunning performance and lightweight, all in one package. The DE1200HD, like the DE300HD, uses a 12AX7 preamp tube to achieve phenomenal tone and EQ flexibility, while improving its output power and decreasing its weight with KUSTOM’s proprietary, high- efficient, Class-D amplifier. The new power amplifier reaches 1200 watts peak, 600 watts continuous, with a built-in limiter that monitors the voltage rails ensuring your sound will not encounter any harsh switching distortion and retain great tone at loud volumes. The preamp features Tube Gain, Bass, Mid and Treble knobs plus dual ROOM EQ sliders (LOW Contour & HIGH Contour) and MASTER Volume, all giving you extreme versatility. The back panel has a Speaker Emulator XLR balanced Line Output, an Effects loop, Power Amp in/out, and two 1/4”/Speakon combination external speaker jacks. This portable head delivers a massive 1200 watts of thunder with real tube tone.
