detuner
Frequency adjustment device
A detuner is a device or mechanism that shifts something away from its standard tuning or frequency.
In music, detuners are attachments for stringed instruments—especially electric guitars and basses—that quickly lower a string's pitch, often dropping the low E to D with a lever flip.
In broadcasting and electronics, a detuner prevents interference by shifting a circuit or antenna away from an unwanted frequency.
He installed a detuner on his bass to get that dropped-D sound without retuning.
