Flexible Bass Tone Shaping

Dedicated Gain and Volume controls make it easy to balance drive and output, while the 3-band Bass, Middle, and Treble EQ provides straightforward control over the overall character of your bass sound. This allows you to adapt the amplifier to different instruments, cabinets, pickups, and musical styles.

Practice, Recording and Playback

The headphone/line output provides a convenient solution for quiet practice and recording, while the Aux In allows you to connect an external music player and play along with backing tracks. These features make the Thunder Bass useful for everyday practice as well as compact recording setups.
