5. Setup

5.1 Power Connection

The Ruby '63 pedal requires a 9 Volts DC power supply. Connect a compatible power adapter to the DC input jack on the pedal. Ensure the power supply meets the specified voltage and current requirements to prevent damage to the unit.

5.2 Audio Connections

Use standard 1/4-inch instrument cables for audio connections. The pedal features a 3.5mm audio hardware interface, typically for auxiliary input or headphone output, but the main input/output for guitar signal will be 1/4-inch jacks.

1. Connect your guitar or other instrument to the INPUT jack of the Ruby '63 pedal.
2. Connect the OUTPUT jack of the Ruby '63 pedal to your amplifier, audio interface, or the next pedal in your signal chain.

5.3 Placement in Signal Chain

As an amplifier emulator, the Ruby '63 pedal is typically placed towards the end of your pedalboard, before time-based effects like delay and reverb, or directly into an audio interface/mixer. Experiment with placement to find the sound that best suits your setup.

6. Operating Instructions

6.1 Powering On/Off

Once the power supply is connected, the pedal will power on. Use the main footswitch to engage or bypass the effect. An LED indicator will typically show the pedal's active status.

6.2 Adjusting Tone

Utilize the various knobs and switches to dial in your desired amplifier tone:

• Volume & Output: Start with these at a moderate level and adjust to match your desired overall loudness.
• Bass & Treble: Shape the low and high frequencies to suit your guitar and musical style.
• Cut: Use this to fine-tune the high-end presence, especially useful for brighter guitars or amps.
• Boost: Increase this control for more gain and saturation, moving from clean tones to rich overdrive.
• Speaker Switch: Experiment with different speaker emulations to find the cabinet sound that complements your tone.
• Amp Mode Switch: This switch alters the internal amplifier circuitry, providing different gain stages and tonal characteristics. Refer to the product's specific documentation for detailed descriptions of each mode.

6.3 Using Footswitches

The pedal typically features two footswitches. One is for engaging/bypassing the main effect, and the other may activate a boost function or switch between presets, depending on the pedal's design. Consult the official Universal Audio documentation for specific footswitch functionalities.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the pedal's exterior. Avoid abrasive cleaners or solvents.
• Storage: Store the pedal in a cool, dry place away from direct sunlight and extreme temperatures. If transporting, use a padded case to protect it from physical damage.
