Build Your Own: Dallas Arbiter Rangemaster Treble Booster

Everything you need to build your own germanium Rangemaster Treble Booster

No expense spared in selecting parts for this build. Each transistor set is tested for gain / leakage and auditioned with a breadboard and amplifier to ensure authentic response and character.

Built around the same eyelet board construction and premium components used in our custom pedals, these kits are designed to deliver both an exceptional fuzz and a rewarding build experience.

Every kit includes a detailed build document featuring clear diagrams, step-by-step instructions, and build photos, along with direct support if questions come up during the build. For builders looking to go deeper, the documentation includes a supplemental section covering circuit analysis, circuit history, and a range of classic mods inspired by vintage and boutique variants.
