Chromatic

Detects any note across the full tuning range. Useful when tuning non‑standard notes beyond standard guitar/bass tuning.

Guitar Standard (G STD)

Tailored for a standard 6‑string guitar tuned E–A–D–G–B–E.

Guitar Compensated (G CPS)

A “compensated” tuning mode — certain strings are slightly detuned (by a few cents) inspired by classical/folk‑style tuning sensibilities.

Bass

Optimized for bass guitars (normally 4-string bass) with appropriate reference notes for bass open‑strings.

James Taylor–Inspired Compensated Tuning

G CPS mode shows slightly adjusted target notes (offset by a few cents) for each string to favour more natural resonance and harmonic richness. Good for acoustic guitars or players looking for a warmer, more organic tonal character.

Multiple Bypass Modes – Expanded

The Flow Tune is designed to integrate seamlessly into any pedalboard without compromising your guitar’s tone.

Bypass Modes

True Bypass

The signal from your guitar completely bypasses the pedal’s internal circuitry – it’s as if the pedal isn’t in your signal chain at all.

Buffered Bypass

The signal passes through a buffer circuit. This slightly strengthens your signal before sending it on to the rest of your chain.

Buffered Monitor Mode

A unique mode that buffers your signal and also keeps your signal "live" so you can monitor your notes while playing.

Flow In Tune

Three display modes that indicates your tune and makes the most out of the bright, colorful LCD screen.
