| Notes | During the rack effects boom of the 1980s, Pro Co introduced the R2DU, which was essentially two RAT circuits in a single rack space box. The two units could be used separately or cascaded together for a more powerful distortion. The R2DU included the RFS-2 dual footswitch for remote control of the unit. |
