Tru-Fi Rangemaster Treble Booster - The Rangemaster one of the original Fuzz pedals of the 60s used by the likes of Ritchie Blackmore and Brian May in Queen give just enough gain and fuzz to push any tube amp over the top. A wonderful pedal to recreate will great rock sounds of the era, but still giving a transparent tone. These pedals are built like tanks, have authentic Mullard OC44 transistors in them to produce the vintage guitar tone you desire.
