Triple Tuner
The Q190 tuner module allows you to keep a watchful eye on the frequencies up to 3 oscillators are producing. Frequencies from all analog oscillators will drift slightly as a result of normal changes in internal cabinet temperature. Now it's easier than ever to ensure your oscillators are doing exactly what you want them to do. Whether you are onstage or in the studio the Q190 is a must have for those patches that need precision from an oscillator or oscillator bank.
If you would like to add the switch jack option to plug directly into an oscillators PCB, please leave a comment on your order with how long you need the jack cables to be
These merchants probably sell this module. Huh?
