Hear it
Rona Audio RA-20 – Chromatic Tuner is a utility pedal in the Vintage Effects collection from Rona Audio: a plug-in recreation of a classic RA-20 chromatic tuner, with the pedal itself as the interface. Every knob, switch and footswitch you see works; the circuit behind them is modelled stage by stage so the controls interact the way the hardware’s do.
- PITCH A4 — The A4 reference the detected pitch is measured against (435-445 Hz, 440 default): sets the note grid and the cents read-out
- OUTPUT — What the output does while the tuner is engaged (footswitch ON): Mute = silent tuning (5 ms fade), Bypass = the signal passes untouched while the tuner listens
- FLAT — Drop-tuning display offset: the shown note is raised by one (b) or two (bb) semitones, so an Eb- or D-tuned guitar reads E A D G B E
- Footswitch — Switches the effect on and off (the LED lights while on).
14 factory presets in 3 categories. Formats: VST3 and AAX (Windows 10/11 64-bit); VST3, AU and AAX (macOS). Mono circuit; in a stereo track both channels are processed identically. Installed, activated and updated with RONA License Manager.
