Quick Start Guide

Step 1: Connect GuitarJack to your device.

Step 2: Start a GuitarJack enabled App. In this example, we will be using FourTrack.

Step 3: Tap on the Song Tools menu. A list of Song Tools will appear. Tap on the GuitarJack Song Tool.

Step 4: Choose which input you plan on using. In this instance, we will be recording a guitar plugged into the 1/4″ jack. Plug your guitar into the 1/4″ jack and headphones into the 1/8″ inch output jack.

Step 5: Set the impedance to whatever setting is needed for your particular use. For guitar, we will set the impedance to Hi-Z.

Step 6: Strum some chords to determine the proper input gain level, and move the slider to select. Be careful not to set it too high so the signal clips.

Step 7: Exit the GuitarJack tool by clicking the arrow icon. Input monitoring is on by default. To hear the input, a track must be armed. Arm a track and you are now ready to begin recording.

GuitarJack Model 2 is now available at Sonoma for $149.00
