Boss TR-2 Tremolo

Faster than the PN-2 and shaped by hand — not by software.

The Boss TR-2 Tremolo is an analog foot pedal for guitarists. It has three knobs: Rate, Depth, and Wave. Rate goes faster than the PN-2. Wave shifts the LFO from triangle to square. It is not rackable.

    What it is

    It is an analog pedal for guitarists — not rackable, not digital, not for keyboards or synths.

  2. 2:07
    How it works

    Three knobs: Rate, Depth, Wave — each does one thing, clearly and directly.

  3. 3:30
    What it does better

    It beats the PN-2 on speed and gives you triangle-to-square waveform shaping — no menus, no modes.

  4. 5:24
    What it leaves out

    No rack mounting, no expression input, no preset storage — it does only what its knobs say it does.

Worth your time?

Yes. Use the whole thing.

3.5/ 5
What works
  • higher-rate tremolo than the PN-2
  • direct triangle-to-square waveform shaping
What does not
  • offer stereo operation
  • accept expression pedal input
  • store presets
  • indicate true bypass status
Use it if
  • guitarists who want fast, hands-on tremolo
Skip it if
  • players needing MIDI, external sync, or stereo routing
The written brief1 min read

What it is and what it was built for

It is an analog tremolo foot pedal built for guitarists. It fits on a pedalboard. It is not rackable.

How it works, in terms a player would use

It uses three knobs: Rate sets pulsing speed, Depth sets intensity, Wave shifts the LFO shape from triangle to square. It is analog. It is not rackable.

What it does better than anything else

It delivers higher-rate tremolo than the PN-2 and gives direct waveform control — triangle to square — in a single-knob sweep.

What it does badly

It offers no modulation depth taper, no footswitchable presets, no true bypass indication, and no way to lock or recall settings.

What people made with it

The sources do not state what people made with it.

Who should use it, and who should not

Guitarists who want immediate, tactile tremolo control should use it. Anyone needing MIDI, expression control, or stereo operation should not.

Is it worth your time

It is worth your time if you need a compact, hands-on analog tremolo with faster rate and waveform shaping. It is not worth your time if you need stereo, expression pedal input, or external sync.

If you can’t find specs for a bass amp head, it’s not a tool — it’s a placeholder.
