Solton TS4 midi controlled sound generator, rhythm and bass unit £249.

This unit accompanies the accordion very well.  It is particularly notable for the incredible array of left hand possibilities as well as right hand settings.  There is advanced programming of the rhythms.  We particularly like settings which use the automatic capabilities but on when triggered by keys/ buttons pressed and find that it adds hugely to the sound produced by the player.

This unit is rack mount but completely encased so can be used free standing.  There are numerous red LEDs to indicate functions selected and an LCD screen to indicate status of the various settings.  The unit is in good condition although it has be used in a rack with some signs minor of use to the casing.
