Dallas Rangemaster Treble Booster – BC109C Guitar Pedal

A single-stage discrete gain circuit built around the BC109C low-noise silicon transistor, the DA-RM is voiced in the tradition of the British sound associated with Tony Iommi and Rory Gallagher.

Refined for clarity, presence, and controlled edge, the DA-RM is voiced entirely by ear to deliver a tight, articulate response with a measured lift in harmonic character.

Designed not to overwhelm an amplifier, but to bring it forward — adding definition, presence, and harmonic density with restraint.

Features

• Original — the classic, focused voicing.
• Mids — increased midrange presence and definition.
• Bass — added low-end weight while retaining clarity and articulation.

Note: Knob color may vary depending on availability.

Each DA-RM is hand built and individually calibrated in Salzburg.

Produced in limited numbers.
Built once. Built deliberately.
