Great Preamp

This preamp is very clean and transparent. It allows the sound of the bass to come through without much coloration. The frequencies for bass, mids, and treble are all well chosen and useful. Achievable sounds range from vintage-y to modern depending on the EQ settings, pickups, and playing techniques. The internal gain trim can be set to keep the signal level even when switching between active and passive, or to boost the active signal to super hot. With the EQ set flat, there is hardly a difference between the active and passive tones. The preamp can be ordered prewired in a number of configurations for to fit many different basses and musical preferences. All in all, this is a high quality preamp that should be considered when thinking about upgrading.
