The Monomyth is a surprisingly capable little bass preamp. It delivers a decent range of overdrive tones, from subtle grit to heavier distortion, and the blend control allows you to retain clarity. It’s a great, affordable option for gigging bassists looking to add some aggression to their sound without needing a complex signal chain.

Frequently Asked Questions

The Voice control pre-shapes the tone with fixed frequencies, offering broader tonal shifts than a traditional EQ’s precise adjustments.
While designed for bass, it *can* be used with guitar, but the lower frequencies will be emphasized, resulting in a very muddy tone unless you dial it back considerably.
The overdrive leans towards a warmer, more rounded character; it’s not a brittle or fizzy distortion, but a more vintage-inspired grit.
