The HBP-1 from Demeter is a hand-wired preamp specifically designed for bass guitar that provides both tube and solid-state tones. It features a high voltage (250V) tube front end with preamp gain and passive tone controls, a two-band solid-state parametric equalizer tuned for bass, and an active effects loop with send and return level controls. In addition, there is a balanced XLR output switchable for a mic or line level signal to connect to a mixer/recording console or a power amp with an XLR input, as well as both balanced and unbalanced 1/4" TRS line level outputs for connection to an amplifier. A dedicated tuner output and a mute switch allow you to tune up silently.
