Reviews and Usability
The Cort CM20B is generally well-regarded as a "best value" option for home practice and low-volume rehearsals.
Sound and Volume: Reviewers from Amazon.com note that it is surprisingly loud for a 20-watt amp and can "definitely keep up with a drummer during band practice" in a controlled volume environment. The sound is described as clear and balanced.
Tone Shaping: The 3-band equalizer allows for a wide range of tonal character, and the "Mode" button is a standout feature for slap-style playing and low-volume practice, offering a full-bodied tone with mid-frequency cut and low/high boosts.
Portability and Build: The amp has a compact size and sturdy, "rock-solid" construction, making it easy to transport and durable for regular use. One user found it to be heavier than expected but attributed this to its quality build.
Practice Features: The Aux-in and headphone jack are consistently praised as useful features for silent practice or playing along with backing tracks from a smartphone or digital music player.
