Normal & Drive Channels

The MA-10B features two dedicated bass channels that can be selected using the DRIVE/NORMAL channel switch.

Normal Channel provides the natural tone of the electric bass, while switching to Drive adds a warm overdriven character for a more driven bass sound.

Combined with the Gain and Tone controls, the two-channel design gives the MA-10B a useful range of bass tones while keeping the control panel simple and straightforward.

10W Full-Frequency Speaker

The MA-10B uses a 5" customised full-frequency speaker designed specifically for the bass version of the MA series.

With a rated output of 10W RMS, the compact speaker delivers a dedicated bass amplification solution without the size and weight of a conventional bass combo.

Two hidden shoulder-strap buckles are built into the sides of the amplifier. When fully rotated, they allow a compatible shoulder strap to be attached.

Note: Shoulder strap is not included.

The built-in Aux In makes it easy to play backing tracks or music through the amplifier alongside your bass.

For quieter playing, the 3.5mm stereo headphone output provides a private listening option. Connecting headphones automatically mutes the internal loudspeaker.
