Ibanez launches TWP10 Twin Peaks wah with dual-inductor circuit
November 3, 2023 · 3 sources
Ibanez has launched the TWP10 Twin Peaks wah pedal, a wah that produces two frequency peaks rather than the usual one, MusicRadar reported on November 3, 20231.
The pedal uses a dual-inductor circuit to create high and low frequency peaks that can be blended1. A Balance dial controls the mix: turning it counterclockwise brings the low-frequency peak forward for what the report describes as a darker, throatier sound, while turning it clockwise emphasizes the high-frequency peak for a brighter tone1. A slider switch selects High or Low frequency modes1. The Level dial has unity gain at 12 o'clock and offers 6dB of boost when turned fully counterclockwise1. The pedal is engaged with a toe-mounted footswitch1.
The sweep ranges differ by mode1:
| Mode | Low-frequency sweep | High-frequency sweep |
|---|---|---|
| Low | 220Hz to 750Hz | 440Hz to 2kHz |
| High | 300Hz to 1kHz | 670Hz to 3kHz |
The TWP10 is true bypass and runs on a 9V battery or DC pedalboard power supply, drawing 15mA1. MusicRadar described the treadle design as vintage Ibanez, close to the retro look of the WH10V3, which remains in the company's lineup with individual voicings for guitar and bass guitar1.
The pedal is available now, priced at $1921. Gearnews reported it as available for pre-order on Thomann at $158.002.
Delicious Audio, in a post updated January 30, 2024, described the Balance control's action in the opposite direction, saying counterclockwise makes the higher-frequency peak more prominent and clockwise makes the lower-frequency peak more prominent3. It gave the same sweep figures for the High mode's high-frequency resonance (670Hz to 3kHz) and the Low mode's low-frequency resonance (300Hz to 1kHz), and described the Level control as having unity gain at 12 o'clock and a +6dB boost at maximum3.
"It uses two peak points at a higher and lower frequency to create the wah effect, instead of one peak point."
