Suhr Discovery Analog Delay




Jack Rabbit is a high quality analog pedal, that delivers a wide variety of tremolo effects – from warm wobble to whacked out. It features simple control over tempo by incorporating both tap, and strum tempo modes. It’s modulation rate spans from 1Hz to 20Hz and utilizes a tempo subdivision switch. The 1/8” stereo TRS input jack called FX LINK allows the pedal to be controlled by an external switch box or effects switching system with TRS control output jacks, such as the BOSS® ES-8 or ES-5.

Tempo Controls

TEMPO SUBDIVISION SWITCH: Jack Rabbit features quarter note, eighth note, and quarter note triplet subdivisions. TAP TEMPO: In addition to using the Rate control, the tempo can be set by using the built in tap tempo and strum tempo modes. Tap tempo is accessed by pressing and holding Jack Rabbit’s footswitch for approximately one second (please see the manual for details).

True Bypass: Jack Rabbit is true bypass via a relay. This function allows for the remote switching, and the battery monitor feature. The relay produces less popping when switching the pedal on and off. FX Link: The FX Link connector allows the pedal’s switching and tap tempo function to be controlled from an external switch, pedal board, loop switcher, or any other custom interface. FX Link also provides the ability to power up in the On/Off state. Low Battery Monitor: A unique battery monitor circuit alerts the user to low battery conditions. In addition, the battery monitor will automatically switch the pedal to True Bypass if the battery voltage is too low for the circuitry to correctly operate.
