The Xotic Bass BB V1.5 Preamp Pedal is a compact analog bass preamp, boost, and overdrive pedal designed to add warmth, punch, clarity, and controlled distortion to your bass tone.

It features four controls:

• Gain: Adjusts the amount of overdrive, from subtle grit to a thicker, more aggressive sound.
• Volume: Controls the output level and lets you boost your signal.
• Bass: Boosts or cuts low frequencies to add depth or tighten the sound.
• Treble: Boosts or cuts high frequencies to add clarity, attack, or warmth.

Key features

• Analog circuitry for a natural, responsive tone.
• Active two-band EQ with up to ±15 dB of adjustment for bass and treble.
• 9V or 18V operation for different headroom and dynamic-response characteristics.
• True-bypass switching to remove the effect from the signal path when disengaged.
• Compact design that fits easily on most pedalboards.
