  • Best Fuzz Pedal

    Verified Purchase

    A very rich, sustained and creamy tone from the Vintage Big Muff Triangle. If you put a Ibanez Tubescreamer before it, the tone and sustain is incredible. The best Fuzz pedal, better than all its descendants. Don't waste time on other fuzz pedals, if you can get hold of one these, you won't be disappointed!

  • The best big muff I've ever heard!

    Verified Purchase

    I have used muff after muff and all were good and have a special place in my heart and I will never forget them. However, when the Triangle Big Muff walked into my life I knew I found what I had missing in my life and it filled the Big Muff shaped hole in my soul.
