Don Butler (Toneman) Rangemaster Treble Booster. This pedal (S/N 1135) was handmade by Don Butler in April of 2000 and is in good condition. Long considered one of the best clones of the original Dallas Arbiter Rangemaster, they are hard to come by as Don stopped making them more than 10 years ago due to not being able to source components that he felt were needed to build a product that he could market as an exact replica of the original circuit. Tested and works as intended, it provides true bypass operation and was built using top notch components. It is missing one screw from the back cover plate (see attached photos) that can't just be replaced as it is stripped. This doesn't prevent cover from remaining firmly in place and does not affect the pedals functionality.
