| Notes | The main difference between this model and the earlier version is the switch from a Tone to the Filter control. The Filter cuts high frequencies as it is turned clockwise. The RAT logo was also switched from an all caps logo to one that was more stylized, while the “a” and “t” were now lower case. |
