TWP10: A new wah sound created by two peak points Traditional wah pedals use a single inductor circuit to boost a specific frequency band (peak point). By moving the pedal, the frequency range that is boosted changes from low to high, creating the characteristic wah pedal sound. The Twin Peaks Wah Pedal TWP10 uses two inductor circuits to boost two peak points, allowing you to change the frequency range by moving the pedal. In addition, you can adjust the balance between the two frequency bands and select a low- or high-frequency range, allowing you to create a wide range of wah sounds, from simple wah sounds to unique wah sounds that use modulation effects. -Features- - Master Level Knob Adjusts the overall output level. At 12 o'clock, the level is similar to a conventional wah pedal, and at full clockwise, it's a +6dB boost level. - Balance control knob: Adjusts the mix level balance of the two peak frequency bands. The high-frequency range is close to the range of a typical traditional wah pedal, while the low-frequency range is close to the range used in custom wah pedals and signature wah pedals. The balance control adjusts the mix level balance of these two frequency bands. At the 0 position (fully counterclockwise), only the high-frequency range is boosted, and as you turn the knob clockwise, the low-frequency range is gradually boosted. At the 12 o'clock position, the high-frequency and low-frequency ranges are at equal levels, and at full position (fully clockwise), only the low-frequency range is boosted. - Tone Mode Switch: You can select the variable range of the two boosted frequency bands from HIGH mode or LOW mode. ○HIGH mode: The high-frequency boost range is adjustable from 670Hz to 3kHz. This is a higher frequency range than typical wah pedals, so the tone may become too bright. If this occurs, we recommend adjusting the balance control or master level, or reducing the high frequencies with your guitar's tone control. The low-frequency boost range is adjustable from 300Hz to 1kHz. This is a slightly lower frequency range than traditional wah pedals. ○LOW mode: The boosted high frequency band ranges from 450Hz to 2kHz. This is roughly the same frequency range as a traditional wah pedal. The low frequency range is from 220Hz to 750Hz. - LED indicator: The LED lights up when the effect is on. If the LED becomes dim or stops lighting up when using batteries, replace the batteries. - Aluminum alloy die-cast body The housing is made of robust and highly durable aluminum alloy die-cast.[Specs] - Controls: Master level, Balance - Switches Effect on/off, Tone mode (High/Low) - I/O's Input, Output - Other True Bypass - Size 96 (W) x 202 (D) x 60-84 (H) (mm) - Weight 815g (including battery) - Required current 15mA @9V - Power supply One 9 volt battery or external DC 9 volt AC adapter (center negative) *When using one 9V (006P) battery or an AC adapter, please purchase a 9V/center negative battery separately.
