Names and Functions

Control Panel

THR30II Wireless

THR10II Wireless
THR10II

1. [ ] (Power Button) / Power Button LED
   This is the unit's power button.
   When the power is ON, the Power Button LED, the lamp corresponding to the selected amp type and the Power Lamp in the speaker cabinet light up.
2. LED Display
   Indicates each of the THR-II's settings and conditions.
3. [TAP/TUNER] button

• Tuner Function
  Holding the switch for 1 second engages the tuner function and lights the indicators.
  The tuner is calibrated to A4=440Hz. Tune the guitar until the desired pitch appears in the LED display.
  When only the circle ( ) in the center of the display is visible, tuning is accurate.
  
  Press the [TAP/TUNER] button (less than one second) to turn OFF the tuner function.
  *When the tuner function is set to ON, the guitar sound to the main speaker, [PHONES] jack, and [USB] jack is muted. The sounds from the [AUX] jack, [USB] jack and Bluetooth are output to the main speaker and [PHONES] jack.
• Tap Tempo Function
  When an ECHO or ECHO/REV effect is selected with the [ECHO/REV] knob!2 control, the tempo of the delay can be set by tapping (more than twice) on the switch.
• Extended Stereo Setting
  Hold the switch for more than three seconds to switch the Extended Stereo* function ON/OFF.
  ON: "#" on LED Display is off (default setting).
  OFF: "#" on LED Display is lit.
  *Extended Stereo: The Extended Stereo function produces a much wider stereo field. Extended Stereo affects the sounds from the [AUX] jack, [USB] jack and Bluetooth as well as the reverb effect.
  *The Extended Stereo setting (ON/OFF) is saved when the power is turned OFF.

4. [AMP] knob
   Selects the amp type. The lamp for the corresponding amp type lights.
   * When the power is turned ON, the most recent amp type is selected.

• Tips on Creating Sound
  Using the [GAIN] knob and [MASTER] knob in combination gives you broad control over the sound for each amp type, except ACO and FLAT. Setting the [GAIN] knob and [MASTER] knob adjusts the amount of preamp and power amp saturation. Once you have the desired sound, use the [GUITAR] knob!3 to set the overall volume of the guitar sound.

5. [AMP] switch (THR30II Wireless only)
   Selects the amp mode. Selects the amp modeling by combination of amp mode and amp type. The [AMP] knob lamp lights for the corresponding amp mode color.
   For further details of amp modeling settings that can be selected by combining the amp mode and amp type, refer to the Amp Modeling List
6. [GAIN] knob
   Adjusts the amount of preamp gain. Turn the knob clockwise to increase the amount of gain.
   * When ACO is selected with the [AMP] knob , the modeled sound is a mixture of the front-mic'd sound and pickup sound of an acoustic electric guitar. (Minimum setting produces the direct pickup sound only. Maximum setting produces the mic sound only.)
7. [MASTER] knob
   Adjusts the volume for the guitar sound. Turn the knob clockwise to increase the volume and create power amp distortion and change in the low-range frequency.
   * When BASS, ACO or FLAT is selected with the [AMP] knob , this only adjusts the volume.
8. [BASS] knob
   Tone adjustment for the guitar's sound. Turn the knob clockwise to enhance the low-range frequencies.
9. [MIDDLE] knob
   Tone adjustment for the guitar's sound. Turn the knob clockwise to enhance the mid-range frequencies.
10. [TREBLE] knob
    Tone adjustment for the guitar's sound. Turn the knob clockwise to enhance the high-range frequencies.
11. [EFFECT] knob
    Selects one of four different effects: CHORUS, FLANGER, PHASER, or TREMOLO. Turn the knob clockwise to increase the amount of each effect.
    * Turn the knob fully counterclockwise to set the effect OFF.
12. [ECHO /REV] knob
    Selects one of four different effects: ECHO (tape echo), ECHO/REV (tape echo/reverb), SPRING (spring reverb), and HALL (hall reverb).
    Turn the knob clockwise to increase the amount of each effect.
    *Turn the knob fully counterclockwise to set the effect OFF.
    *When ECHO or ECHO/REV is selected, the [TAP/TUNER] button can be used to set the delay time.
13. [GUITAR] knob
    Adjusts the overall volume of the guitar sound.
    *This knob's setting has no effect on the signal sent to the [USB] jack .
    *The volume output to the [LINE OUT] [L] [R] jack (THR30II Wireless only) is constant regardless of the setting of the [GUI-TAR] knob.
14. [AUDIO] knob
    Adjusts the audio playback volume for audio from the computer connected to the [USB] jack , an audio device connected to the [AUX] jack , or a smart device connected by Bluetooth
15. [INPUT] jack
    This is a standard phone jack used to connect a guitar to the THR-II.
    *Connecting the Relay G10T to the [INPUT] jack starts charging that device automatically. (THR-II Wireless only)
    *The optimal channel is set automatically by connecting the Relay G10T to the [INPUT] jack for at least 10 seconds. (THR-II Wireless only)

Amp Modeling List

Mode	Amp Type	Description
Classic	Clean	A low-gain preamp for sparkling American-style cleans, with 6L6 tubes in the output stage for brightness and a strong midrange.
	Crunch	EL84 power tubes in a true Class-A configuration with a highly responsive EQ for rich, complex harmonic tones and warm overdrive. Inspired by British chime.
	Lead	A low-gain preamp with an EL34-based power section that breaks into classic British overdrive as the master volume is pushed.
	Hi Gain	Powerful modern distortion that fills out as the high-gain preamp is pushed. Tread carefully after 12 o'clock.
	Special	12AX7 and 6L6 tubes in pursuit of the "Brown" sound. Set the gain around 11 o'clock for classic rock crunch, or crank it for saturated rhythm tones.
	Bass	Woody, vintage tone with late breakup.
	Acoustic	Designed for acoustic-electric guitar, modeling the response of a boutique condenser microphone.
	Flat	A neutral tone with no amp or speaker modeling. Great for connecting other instruments to your THR.
Boutique	Clean	A low-watt EL34 design. Turning up the preamp gain will thicken up the cleans, then push into bluesy overdrive.
	Crunch	A deceptively simple amp circuit with just a single 12AX7 and EL84. A full, no-frills tone that is highly responsive to picking dynamics.
	Lead	A version of the Classic/Lead circuit, modified for extra gain with a darker tone and scooped mids.
	Hi Gain	ECC83s into 6L6s for high gain with a highly responsive EQ, inspired by German engineering.
	Special	Four 12AX7 preamp tubes into 6L6 output tubes. Tight, fast tracking for crushing highgain.
	Bass	Full, modern tone that breaks into a fuzz-like overdrive when pushed hard.
	Acoustic	Designed for acoustic-electric guitar, modeling the response of a boutique tube microphone.
	Flat	A neutral tone with no amp or speaker modeling, and a slight bass boost. Great for connecting other instruments to your THR.
Modern	Clean	A boutique, low-watt EL84 design that adds fullness and sustain as the master volume is turned up. A great match for neck pickups.
	Crunch	A mid-volume boutique design with 6550 power tubes. Listen for tight bass response and a singing sustain.
	Lead	A high-gain design with 12AX7s into EL34s, for the tone that defined 1980s hard rock and heavy metal.
	Hi Gain	A boosted version of the Classic/Special amp, with even more gain for aggressive rhythms or searing leads.
	Special	A classic overdrive circuit before the preamp tightens low-frequency response and provides even more gain. Ideal for extended-range guitars.
	Bass	Vintage voicing with early breakup for overdrive that works well with bass or guitar.
	Acoustic	Designed for acoustic-electric guitar, modeling the response of a boutique dynamic microphone.
	Flat	A neutral tone with no amp or speaker modeling, and a slight mid scoop. Great for connecting other instruments to your THR.
