Take off the classic Rangemaster Treble Boost, used by Brian May of Queen, Sabbath and Deep Purple. The beauty of the Rangemaster is it takes a mild overdriven tube guitar amp and push's it into outer space for the classic Crunch Rock sound. These pedals are made like the rest of the Tru-Fi line with lots of love and time,

They are built with REAL OC44 Mullard Black Glass Transistors
