Overview
  • 1Description

The HBP-1J with Jensen Transformer 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.

Balanced and Unbalanced Outputs
A fully balanced XLR line output is provided to feed the audio signal from your bass to an external mixing console
Active and Passive Inputs
Separate inputs are provided to connect active and passive instruments
Tube Front End
The HBP-1 uses a 12AX7a tube on the front end for gain and passive tone controls
Adjustable Effects Loop
