Boss TR-2 Tremolo Settings Guide

The Boss TR-2 is the standard compact tremolo pedal — volume-based tremolo (amplitude modulation) with Rate, Wave, and Depth controls. The Wave control moves the LFO shape from triangle (smooth, rounded tremolo) to square (choppy, rhythmically abrupt). One of the most popular tremolo pedals on any budget, widely used in country, surf, blues, and indie rock.

The best Boss TR-2 Tremolo settings start with: Rate at 5/10, Wave at 4/10, Depth at 6/10. Adjust from there based on your amp, guitar, and room volume. For Country / Vintage: Rate 5/10, Wave 3/10, Depth 7/10.

What Each Control Does

LFO waveform — triangle = smooth; square = choppy

Settings by Genre

Country / Vintage
Rate5
Wave3
Depth7

Triangle wave at moderate Rate with generous Depth — the smooth, pump-like tremolo that Fender amps built in from the 1950s onward. Wave at 3 (just below centre, toward triangle) produces the rounded, musical oscillation that vintage tremolo fans prefer. Depth at 7 makes the effect clearly audible.

Surf
Rate7
Wave5
Depth8

Fast Rate with centred Wave and deep Depth — surf tremolo is fast and dramatic. At Rate 7 and Depth 8, the TR-2 produces the rapid, stuttering tremolo effect of classic surf recordings. Wave at 5 (centre) provides a balance between smooth and choppy.

Indie / Shoegaze
Rate3
Wave5
Depth5

Slow Rate with moderate settings — slow tremolo adds movement to clean or lightly overdriven chord playing without dominating. Wave centred produces a smooth but present oscillation. Used in indie and shoegaze as a subtle rhythmic element beneath sustained chords.

Stutter (square)
Rate6
Wave9
Depth9

Square wave at high Rate and Depth — the choppy, rhythmic stutter tremolo. Square wave means the volume snaps abruptly from on to off rather than smoothly oscillating, producing a gated effect. At high Rate the notes chop in a rapid rhythmic pattern useful for rhythmic interest in post-rock and experimental contexts.

Tips & Common Mistakes

  • The Wave control is the TR-2's most distinctive feature — it allows the tremolo shape to be dialled between smooth triangle (like a vintage amp tremolo) and choppy square wave (like a gated effect) continuously. Most vintage amp tremolos are fixed at triangle wave; the TR-2's flexibility covers vintage through to modern rhythmic stutter.
  • The TR-2's volume-based tremolo (amplitude modulation) means it creates volume oscillation rather than pitch oscillation. True vibrato (pitch modulation) is different — Fender's "Vibrato" channel on vintage Fenders is actually tremolo; true vibrato is rarer. The TR-2 is amplitude-based, as are most tremolo pedals.
