This simple mod includes the necessary parts, diagrams & instructions for making your vibrato MUCH more sexy. It slows down the “slow end” of the vibrato effect considerably, giving a much wider useable “speed” range, with emphasis on the slower speeds & pulses. The faster speeds remain virtually unchanged. The intensity remains the same.
The official Fender “vibrato tick cure”, issued as an official service report in the 70’s, is also included in this kit (“tick cure” is for two channel amp vibrato types with an “optocoupler”, not applicable to the Princeton & Champ vibrato circuits).
