Jon Johnson Report post Posted April 10, 2017 The Ace Tone FR-2L is the successor to the F-1. This unit retained the 4 drum instruments but two of the cancel buttons removed but instead allowed cancel buttons for the clave, snare, and cymbal sounds. The casing was slimmed down to allow the user to place the instrument on top of an organ or keyboard. The control panel was largely the same but in reversed rder from the FR-1L with the same 16 preset buttons, cancel buttns and control knobs.
