WELCOME
Congratulations on your purchase of the Electro-Harmonix EHX-2020 Chromatic Tuner Pedal, a
convenient and complete solution to tuning your instrument.
FEATURES & FUNCTIONS
1) Foot Switch: Pressing the Foot Switch will turn the tuner on/off.
2) Input Jack: Connect the cable from your instrument to the Input Jack of the tuner. When
powering the tuner from a battery, the Input Jack also functions as a power switch. Battery
power is engaged when a plug is inserted into the Input Jack. Power shuts off when the plug
is pulled out of the Input Jack. We recommend you remove the plug from the Input Jack
when you finish playing music.
3) DC 9V In Jack: If a DC adapter is used, you will be able to play without worrying about battery
life.
4) Output Jack: Connect your amp or another effect unit to the Output Jack. When the tuner is
off, the Output Jack will output the signal of the instrument connected to the Input Jack.
When the tuner is on, no sound will be output from the Output Jack so you can tune silently.
5) Pitch Button: This button lets you change the reference frequency. 7-segment indication of 0
to 5 means 440-445Hz, and an indication of 6 to 9 means 436-439Hz.
6) Flat Button: This button lets you use flat tunings.
Normal Tuning: Detuned ½ Note: Detuned 1 Full Note: Detuned 1 ½ Notes:
