Angelo Marruzzi started cloning classic pedals in the early 80's, even before they were considered classic, starting with a Germanium Vox Tonebender circuit after he found an old dead Vox organ with tons of the same Italian germaniums in it that the Tonebender used. He also went to the UK to go digging up real Mullard germanium transistors long before anyone else.

    In 1995, when most people didn't even know what a rangemaster was, he released the first commercially available Rangemaster clone (1995-2003), which has been used by Tony Iommi, Brian May, KK Downing and Glen Tipton from Judas Priest, R Blackmore, Slash, Steven Seagal,...

    The Gammatronics pedals, clones and own designs, are still very sought after: the G-Spot Overdrive Preamp, the Octavia pedal, and the Fuzzface clones with real BC108C Telefunken transistors.

    As a professional musician/composer/engineer, Angelo Marruzzi preferred doing music, so he stopped making Gammatronics pedals. He still makes a unit from time to time, when time permits, for pros who absolutely have to have them.

    Gammatronics started in approx 1995 in Los Angeles, California, USA.

    Timeline (by Angelo Marruzzi)

    • Early-80's: Fisrt started fixing/modding/building pedals.
    • 1988: Designed and built the G-Spot Overdrive, a discrete FET OD design that probably predates all of the popular circuits that exist like that today.
    • Mid-90's: Gammatronics was founded when I came out with the first Rangemaster treble Booster clone, called the "Derangemaster Trouble Booster". Hardly anybody even knew what that pedal was, and how many important guitarists had used it. They sold like hotcakes.
    • Approx 2005: With everything else going on, I got too busy to keep making all the pedals that people needed, so I really limited production at that time.
