Blackstar Unity Bass U120 Bass Amp Settings

Here’s a list of recommended amp settings to help you get the most out of your Blackstar Unity Bass U120 based on different playing styles and tones. These settings utilize the available controls: Gain with clip LED, Pad switch, Voice switch (Classic/Modern/Flat), 3-band EQ with sweepable mid, Compressor, Chorus, Response control, and Master Volume.
