Yes, the Sonar is a “tremolo” pedal, but this one’s different. This unit has the ability to chop up any signal you send into or out of it. Unlike most other tremolos, it can cut down your high gain signal to silence. It can also sound gorgeously transparent like a traditional tremolo. It does other fun stuff like increase or decrease tempo, duty cycle (amount of time the trem is on in a given cycle), or both simultaneously on the fly. It also has tap tempo and a slew of advanced features (attack, release, and depth controls). Lastly, and perhaps most importantly, it has a famed Z.Vex “Machine” circuit built right into the box.
Plug your guitar into the input jack and your amp into the output jack (or you might mix it with other pedals). It can be anywhere in the chain, but if you are using it in “Machine” mode you might want to put it before other dirt boxes to hear it cut through those effects. Please refer to the “Machine” documentation for more information on that effect.
- Volume: Park this all the way clockwise for slightly over unity gain. If you need more gain (on either “clean” or “machine” modes), a trimmer is inside the pedal that can be pushed harder clockwise. This will break-up the “clean” signal though.
- Speed: Manual control of tempo Attack: Controls how quickly audio reaches peak volume of tremolo
- Duty: Controls duration of peak audio, the “on” portion of tremolo
- Release: Controls how quickly audio ramps down from peak
- Delta: Controls the rate of change when unit is in “Arrow Up/Down Mode”
- Depth: Controls minimum volume of quiet portion of tremolo
Hidden functions accessed by pressing and holding the tap tempo switch.
Battery & Power Supply
The Sonar draws about 10mA and can be powered with a 9V battery (remove the four screws on the bottom for replacement) or any standard fi ltered/regulated musical 9VDC power supply with a Boss-style connector (negative-tip barrel connector). We recommend using an alkaline 9V battery but a carbon-zinc battery (shipped with the unit) will work.
