The Cort CM20B is a compact and reliable 20-watt bass combo designed for players who want solid tone and simple control in a practical size. Perfect for beginners, students, and home practice, it delivers punchy low end and clear definition without taking up much space.

Featuring an 8” speaker and a responsive 3-band EQ (Bass, Middle, Treble), the CM20B allows you to shape your sound easily — from warm and rounded to bright and articulate. The built-in mode switch enhances lows and highs while scooping mids for a fuller, more modern bass tone.

An auxiliary input lets you play along to backing tracks, and the headphone output makes silent practice easy — ideal for late nights or shared spaces.

Simple, dependable, and affordable — the CM20B is a great entry-level bass amp that gets the job done.
