Quick guide from the manual
The Free The Tone RED JASPER (RJ-2V) is a low-gain overdrive pedal designed to provide responsive, tube-like compression. Key operational points include:
- Internal Switches: The pedal features two internal switches (SW1 and SW2) to adjust low-end frequency characteristics.
- Battery Monitoring: The LED indicator dims when battery voltage drops below 6V, signaling a need for replacement.
- Safety: Always turn off or mute your amplifier before connecting or disconnecting cables to prevent speaker damage.
About the Product
The RED JASPER is a versatile overdrive pedal that can be used for comping, adding character to a clean signal, or as a booster. It is equipped with the HTS (Holistic Tonal Solution) circuit, which ensures the bypassed signal remains clear and retains its tonality.
Internal Switch Settings
You can customize the low-end frequency response using the two internal switches. The cut-off of the bass range becomes progressively stronger from setting A to D.
- Setting A: SW1 ON / SW2 ON
- Setting B: SW1 ON / SW2 OFF
- Setting C: SW1 OFF / SW2 ON (Factory default setting)
- Setting D: SW1 OFF / SW2 OFF
Battery and LED Indicator
The LED indicator serves a dual purpose: it shows the effect status (on/off) and monitors battery voltage. If the LED starts to dim, the battery voltage has dropped below approximately 6V. While the effect will still function, it is recommended to replace the battery to maintain optimal performance.
Precautions
- Connection Safety: Do not insert or remove plugs from the input jack while the output is connected to an active amplifier or speaker system, as this can cause noise that may damage your equipment.
- Storage: If the unit will not be used for an extended period, remove the battery to prevent damage from chemical leakage.
- Malfunctions: If the unit behaves abnormally, cease operation immediately and contact your supplier.

Practical help
Common problems
Effect sound is weak, drops in level, or produces no output.
The battery voltage is likely too low. Replace the battery with a new one.
Loud noise when plugging in or unplugging the pedal.
Ensure the amplifier is turned off or the volume is muted before connecting or disconnecting cables to prevent damage to speakers.
Before use
- Ensure you have a fresh 9V battery or a compatible AC adapter.
- Turn off or mute your amplifier before making connections.
- Check the internal switch settings (SW1/SW2) to ensure they are configured to your preferred low-end response.
- Verify that the input and output cables are securely connected.
Specs in practice
- Input Impedance: 390kΩ
- Determines how the pedal interacts with your guitar pickups; this value is optimized for standard guitar signals.
- Current Consumption: 11 mA
- The amount of power the pedal draws; ensure your power supply can provide at least this amount.
- Output Load Impedance: min. 10kΩ
- The minimum impedance the pedal can drive; ensures compatibility with standard guitar amplifiers.
Images and diagrams
- The internal switch diagram shows two switches (1 and 2). Setting C is the factory default. Settings A through D adjust the low-end frequency cut-off, with D being the strongest cut.
Model compatibility
- Requires 9V DC power supply or 9V battery.
- Compatible with standard 1/4 inch instrument cables.
