The CM15R offers a wide range of clean and overdrive sounds with a sparkling clean channel and a rich-sounding overdrive channel with independent gain and volume controls and a 3-band EQ with the treble, middle and bass knobs specifically tailored to the sonic range of the electric guitar. The gain control provides a wide range of overdrive from bluesy crunch to over-the-top modern distortion. The push-button channel selector allows you to switch from the clean channel to overdrive/distortion channel and back easily, making the CM15R a very versatile amp in its class. The built-in digital reverb adds lush ambience to your guitar sounds, making your practice sessions that much more enjoyable and effective. The compact 8” speaker is efficient with plenty of power-handling capacity and can get surprisingly loud, making it ideal for practice with other band members in a controlled volume environment. The sound is clear and balanced, allowing your playing style and character to come through without coloration. The Auxiliary input allows you to connect your smartphone or digital music player to the amplifier and play along with your favorite music. The headphone jack can be used to practice late at night or in quiet environments, making the CM15R a versatile amp that can be used in variety of playing situations.
