    Along with distortion and delay, the wah-wah is part of the “Holy Trinity” of classic guitar effects. Invented by accident in the 1960s, the wah-wah can make a guitar sing, laugh, cry and scream like human being. It’s a powerful effect that’s helped take solos by Hendrix, Clapton and a thousand guitarists since to the highest echelons of classic rockdom. Now, T-Rex is proud to introduce Gull, our own interpretation of the wah-wah legend.


    Two wahs and the long-forgotten yoy

    Many of the wah-wah pedals produced over the decades are very different from each other. And then there are related effects – like the underrated (we think) yoy-yoy pedal. When we designed Gull, we wanted to bring you the very best that history has to offer – and then some.

    Gull gives you two distinct wah-wah sounds – a light wah that’s great for clean guitars and rhythm parts and a heavy, smoking wah for distorted leads – plus the unique dual-filter yoy-yoy effect. Yoy-yoy is a basically a wah effect with an ultra-high-frequency sweep soaring overhead. It’s an incredibly rich sound.

    A classic SLOPE knob lets you shape the character of your wah/yoy sweep, and a BOOST function lets you set a higher volume for your output signal when you kick your Gull into action.

      Tribute to the old Mercedes Gull Wing 300 SL

      • Inspired by the vintage Mercedes 300SL Gull Wing car
      • A truly unique voice that’s still rooted in the classic Vintage Wah’s
      • 3 Wahs in one box - offers a lot of flexibility and options
      • Great boost and voicing control that can help you reshape your sound
      • Hotspot button changes the action of the foot pedal
      • Hendrix sound in a brilliant design!

      A more musical wah

      With Gull, we also wanted to address a complaint many guitarists have with traditional wah-wah pedals: their response. Wah-wahs often jump into action at the slightest touch, leaving little room to work the pedal and build up slowly.

      Gull addresses this with a special HOTSPOT button that gives you the option of slowing the onset of the effect and using the whole pedal to “wah” with. It makes Gull respond more like a musical instrument than many legacy pedals do.

      We truly believe that the T-Rex Gull is the wah-wah the world’s been waiting for. Try it today at your local music store.
