The Acoustic Image CODA S4 1-channel is a highly portable combo amplifier with two channels and 600 watts of clear-yet-robust AI sound. Plus effects for those who insist.

In this newest version of the little combo amp that started a revolution of sorts, Acoustic Image has improved fidelity while lowering self-noise even further, provided for additional speaker protection, added a limiter switch to smooth the signal during extreme volume playing situations, and changed the speaker to a ceramic magnet volume for more note definition and articulation.

The Acoustic Image CODA is an outstanding way to amplify acoustic bass, classical guitar, piano, woodwinds, voice and other full range musical instruments due to its sonic transparency and the unique way in which it disperses the soundstage.

The CODA S4 features the Acoustic Image Cabrio Docking System which allows for easy removal of the head for recording or powering another cab...and re-insertion into the combo afterwards. Acoustic Image calls it "separation without anxiety" but we like to think of this mechanism as simply and example of AI's pragmantic imagination.
