Distortion PreAmp
The Alpha·Omega Ultra is the most versatile bass preamplifier we’ve designed: With its two distinct distortion circuits (Alpha and Omega), extremely high dynamic range, six-band active graphic EQ, dedicated headphone output and balanced direct output with switchable digital impulse-response cabinet emulation make for an incredibly complete tool for the modern bass player.
