The Boss PC-2 Percussion Synthesizer is a stompbox that generates its own percussion sounds rather than processing your guitar's signal. RockBoard's PedalPedia describes it as synthesizing analog drum, laser, and sci-fi percussion effects within a standard stompbox enclosure, and it can be played from a drum pad, a trigger, or pulses coming down the input1. It belongs to the wider family of drum pedals and synth pedals that let a guitarist add percussion from the board.
How it works and how it is triggered
Inside, the PC-2 uses pure analog synthesis architecture built around a voltage-controlled oscillator and an envelope generator1. In practical terms, an incoming strike or pulse fires the envelope, and the oscillator produces the tone that envelope shapes. Because it synthesizes rather than plays samples, the sound is fully analog from trigger to output.
The pedal accepts three kinds of trigger, and a dedicated sensitivity knob balances the input gain to accommodate them1:
- Piezo sensors
- Drum triggers
- Incoming audio pulses1
It also responds dynamically to input strike strength, so hitting a pad harder changes the sound the PC-2 produces1.
The controls
Five dedicated rotary controls govern the sonic contour of the analog oscillator1:
| Control | What it does |
|---|---|
| Sensitivity | Balances input gain to suit piezo sensors, drum triggers or incoming audio pulses1 |
| Pitch | Sets the oscillator's pitch1 |
| Decay | Shapes how the sound falls away1 |
| Sweep | Shapes the tonal contour of the oscillator1 |
| Pitch-bend depth | Sets how much pitch bend is applied1 |
Connections and power
The PC-2 has a dedicated quarter-inch trigger input for external pads1. On the output side, the unit routes monaural analog output directly into standard guitar amplifiers, bass rigs, or PA mixing consoles, so it slots into a normal rig without special hardware1.
Power comes from a 9V DC, center-negative supply drawing 9mA1. That is a light, standard draw, so it sits comfortably on a pedalboard power supply.
The PC-2's output is mono, so a single feed to an amp, bass rig or PA channel carries the sound; there is no stereo output1.
Where it sits among the alternatives
The PC-2 is a sound generator you play from a pad or trigger, which sets it apart from pedals that play back recorded rhythms. Loopers and drum machine pedals such as the Singular Sound BeatBuddy 2, the DigiTech SDRUM or the Boss DRP-1 Dr. Pad provide beats and patterns, while analog percussion synths like the VERMONA BASS|DRUM or the Mattoverse Electronics Mattoverse Analog Kick Drum MKII generate their own tones the way the PC-2 does.

Questions
Is the Boss PC-2 analog or digital?
The PC-2 is an analog pedal. Its internal circuitry uses pure analog synthesis architecture built around a voltage-controlled oscillator and an envelope generator, rather than digital sample playback. That analog oscillator is what the pitch, decay, sweep and pitch-bend depth controls shape.
Can I trigger the Boss PC-2 with a drum pad?
Yes. The PC-2 has a dedicated quarter-inch trigger input for external pads. The sensitivity knob balances the input gain to accommodate piezo sensors, drum triggers or incoming audio pulses, and the unit responds dynamically to input strike strength.
Does the Boss PC-2 take a battery?
The PC-2 runs on a 9V DC, center-negative power supply drawing 9mA. No battery option is documented for the pedal, so plan to use a standard Boss-style adapter.
Is the Boss PC-2 output mono or stereo?
The PC-2 output is mono. The unit routes a monaural analog output directly into standard guitar amplifiers, bass rigs or PA mixing consoles.
What sounds can the Boss PC-2 make?
The PC-2 synthesizes analog drum, laser and sci-fi percussion effects within a standard stompbox enclosure. Its five rotary controls, covering sensitivity, pitch, decay, sweep and pitch-bend depth, govern the sonic contour of the analog oscillator, so tones range from percussive drum hits to sweeping laser and science-fiction style effects.
