Built with vintage parts by me here in the UK no pcbs here nearly everything dating back to the 60s including a mullard OC45 transistor, this really is a taste of those golden years.

The unit has only been mildly altered to reduce some of the famous noise that the originals were known for, in addition input switching allows a little more tone shaping, turning this into pretty much a full on boost pedal.

Combined with the ability to use a 9v power supply your really getting best of the 60s with a modern sprinkle of magic. 

The original units made famous by toni iommi, Eric Clapton, Rory Gallagher to name but a few, used to drive those big old amps into rock history, don’t be misguided by the described function ‘treble boost’ ! A rangemaster is a BOOST pedal and will take any amp into a sublime vintage tone somewhere between overdrive and boost. Even solid state amps take on a different dimension. But In front of a valve amp they come alive. You will cut through any mix with one of these.
