Jam 150 Stereo - STICK (Ex Demonstration)

Equally brilliant in mono or stereo applications the speaker configuration and output is the same as the Jam 150 Plus but the mixer has a different layout and stereo capabilities when a second active speaker cabinet is added to the system.

Jam 150 Plus ( Ex Demonstration )

Designed with the acoustic guitar as its primary partner, the Jam 150 Plus has nevertheless become a firm favourite for a wide range of other acoustic and electronic instrument sound sources where tonal accuracy, dynamic response and purity of reproduction are the primary requirements.
