Congratulations on your purchase of the Nano Pulsar, a variable shape stereo tremolo, and panner effects pedal. Connected in mono, the Nano Pulsar is a tremolo that allows significant control over the shape of the modulating waveform. Connect the Nano Pulsar in stereo (each output to a separate amp/ mixer channel) and you have a panner pedal that will send your instrument back and forth between two amps with the same control over waveform shape. So, while one amp is fading up in volume, the other will be fading down in volume or even more dramatic: while one amp is on, the other is off. But that’s not all! Higher settings of the DEPTH knob put the Nano Pulsar into warp mode where the signal’s volume modulates asymmetrically producing rhythmic, out-of- phase tremolo effects.
Operating Instructions
Connect your guitar or another instrument to the INPUT jack on the Nano Pulsar
and the MONO/L OUTPUT to your main amp. If running the Nano Pulsar in stereo,
connect the Right OUTPUT jack to another amplifier. Apply power if needed;
your Nano Pulsar might already have a 9V battery installed. Press the
footswitch to ensure the STATUS LED is lit, now your Nano Pulsar is ready to
go.
For a nice starter set, turn all knobs to their 12 o’clock positions and set
the toggle switch—centered within the knobs—to the Triangle position. This
setting will yield a deep, smooth tremolo at a medium rate. Lower the DEPTH
knob for a shallower tremolo effect; play with the RATE knob to hear the full
range of modulation speed on tap; and of course, adjust the VOL knob for more
or less volume at the output jacks.
Controls and Connections
-
VOL Knob Adjusts the overall output level of the effect. As VOL is turned clockwise, the output gets louder. The VOL knob offers up to 12dB of volume boost depending on the settings of the other controls. When VOL is turned fully counterclockwise the effect output is silenced.
-
SHAPE Switch Selects between Triangle and Square Wave modes. See more on Shape in the SHAPE knob section.
-
SHAPE Knob Further adjusts the tremolo’s modulation waveform shape.
Triangle Wave Mode The modulation waveform is triangle wave-based, resulting in smooth volume modulation. As the SHAPE knob is turned clockwise from the minimum position to the center, the waveform morphs from a rising sawtooth to a triangle. Turning SHAPE further clockwise from the center position to maximum, the waveform continues to morph from triangle to falling sawtooth. Please note: the triangle shapes are reversed out of the Right OUTPUT jack. For example, at the minimum SHAPE setting, the right output will be a falling sawtooth.
Square Wave Mode The modulation waveform is square wave-based, resulting in sharp, on/off volume modulation. As the SHAPE knob is turned clockwise from minimum to maximum, the modulating waveform’s pulse width increases from a narrow pulse to wide pulse width. Near the knob’s center position is square wave modulation where the tremolo volume is loud and quiet in equal amounts. Please note: the square shapes are reversed out of the Right OUTPUT jack. For example, at the minimum SHAPE setting, the right output will be a wide pulse width. -
DEPTH Knob Adjusts the amount of tremolo that will be applied to your signal. As DEPTH is turned clockwise from minimum to maximum, the amount of the tremolo effect increases. Maximum tremolo—the greatest dynamic range from loudest to quietest—occurs when the DEPTH knob is set to approximately 1 o’clock. As DEPTH is turned further clockwise past 1 o’clock, the tremolo begins to warp by modulating between positive and negative phases with an asymmetric or rhythmic feel. Set DEPTH to approximately 1 o’clock to obtain the widest stereo field when the Nano Pulsar is used as a stereo panner.
-
RATE Knob Adjusts the speed of the tremolo or pan effect. As RATE is turned clockwise the modulation rate increases. The range of modulation speed is approximately 20 seconds to 30 Hz.
-
FOOTSWITCH and STATUS LED – Press and release the footswitch to toggle between buffered bypass and effect mode. When in effect mode, the Status LED is lit and pulses at the same rate as the effect. The Status LED is off in buffered bypass mode. The Nano Pulsar powers up in bypass mode.
-
INPUT Jack Audio input to the Nano Pulsar.
-
MONO/LEFT OUTPUT Jack Connect this ¼” mono jack to your amplifier’s input. When using the Nano Pulsar as a mono device we recommend you use the MONO/L jack so that the SHAPE knob description on the previous page corresponds to what you hear.
-
RIGHT OUTPUT Jack Connect this ¼” mono jack to your second amplifier’s input. When using the Nano Pulsar as a stereo panner, use the R OUTPUT jack for your second channel. You can connect only to the RIGHT OUT jack if you like; the tremolo effect will be the same as from the LEFT OUT jack but the SHAPE waveforms are reversed. For example, when the SHAPE knob is set to maximum, tremolo modulation out of the Right Output will either be a rising sawtooth or narrow pulse width.
-
9V Power Jack – An optional 9VDC, the center-negative power supply can be connected to the power jack to provide power without a battery. The Nano Pulsar requires 30mA at 9VDC on a center-negative plug. Do not exceed 12VDC at the power jack. When using a 9V battery, plugging into the INPUT jack activates power. The input cable should be removed when the unit is not in use to avoid running down the battery.
To change the 9-volt battery, you must remove the 4 screws on the bottom of the Nano Pulsar. Once the screws are removed, you can take off the bottom plate and change the battery. Please do not touch the circuit board while the bottom plate is off or you risk damaging a component.
Notes and Specifications
