EBS Session 30 MK3 30-Watt Bass Combo Amplifier

The EBS Session 30 Mk3 is one of the most compact 30W bass combos available today, featuring an analog, great-sounding design and tools that make practice perfect.

Now equipped with a tweeter and Bluetooth audio streaming, this combo lets you play along with music wirelessly and delivers improved sound quality.
The Session 30 Mk3 is designed to help you grow as a bass player by providing an honest, natural tone that reveals areas for improvement and rewards your progress. Bluetooth streaming allows you to connect your smartphone or tablet without any cords, and plugging in headphones automatically mutes the speaker for quiet practice.

An upgraded 8-inch speaker and added tweeter enhance both your bass sound and the quality of streamed audio. Use the XLR recording output to connect directly to your recording interface or mixing console without needing an external DI box. Note that the recording output excludes the streamed audio.

Key features include professional-grade EQ filters to shape your tone, Bluetooth streaming for play-along music, a headphones output for late-night sessions, and an XLR output for easy connection to recording or live sound setups.

Ideal for players who want a transparent, authentic amp to hear every detail of their instrument, the EBS Session 30 Mk3 is perfect for practice, warm-up, or as a reliable small rig for seasoned players with high-quality instruments. It delivers clear, high-quality tone in a tiny, portable package.
