Jam series combos were specifically designed with the acoustic instrumental performer in mind and are the perfect choice for those musicians who wish to hear the true sound of their acoustic instrument amplified. The extraordinary balance, detail and dynamic response of every Jam combo allows total expression for the artist, regardless of their musical style or performance level, and the numerous facilities on the Jam series allows quality EQ and effects to be introduced into the audio chain as required. 

SR realised that many of the performers who wanted the very best acoustic amplification would also want to successfully amplify other signals such as vocals, recorded music and other instruments to the same high standards. The challenge for SR therefore was to design a single combo that could rise to all these tasks without compromising any aspect of the original aim. In this task SR have been remarkably successful. Not only is the Jam a first choice for discerning acoustic players all over the world but it is also in demand by a whole range of other musicians such as pianists, vocalists and Jazz guitarists amongst others. 

Most Jam models are available in 3 quality finishes, moquette, lacquered black and polished wood. A range of high quality carry cases and other accessories are also available. To view a full Jam series specification sheet just click here
