Suhr Brighton Treble Guitar Effect

Suhr Brighton Treble Booster — Classic Rangemaster Character, Modern Control

The Suhr Brighton Treble Booster is an analog boost pedal built to deliver the harmonically rich, upper-frequency lift that defined legendary Rangemaster tones used by Brian May, Tony Iommi, and early Judas Priest. Rather than acting as a transparent clean boost, the Brighton is designed to become a major component of the guitar sound itself, kicking a dark or neutral-voiced tube amplifier into saturated, singing overdrive while preserving every nuance of picking dynamics. The pedal focuses its energy on the upper midrange and treble frequencies, tightening low end and pushing notes forward so they cut through dense mixes without sounding harsh.

Standout Features

What separates this pedal from a vintage Rangemaster is its expanded control layout. A dedicated Body knob blends in significantly more low end than a stock treble booster, allowing the circuit to pair with brighter amplifiers that would normally reject a classic unit. The 2-position Smooth switch rounds off the very top of the frequency response, shifting the overall character from a glassy, aggressive edge to a warmer, more vocal lead voice. Together with the Bias control, which adjusts the intensity and harmonic content of the boosted signal, the Brighton adapts to a far wider range of amps than its single-sound predecessors.

Controls and Interface

The top-mounted control set is intentionally simple, giving players immediate access to the three parameters that shape the booster's voice without menu-diving or hidden dip switches. Each knob responds in real time to playing dynamics, so volume rolling on the guitar itself becomes part of the tone-shaping process.

• Treble: Large central knob — sets the amount of upper-frequency lift and overall boost level sent to the amplifier
• Bias: Side knob — fine-tunes the intensity of the boosted signal and adds harmonic distortion and natural breakup
• Body: Side knob — blends in low-end depth to add fullness and tame overly bright amplifier pairings
• Smooth: 2-position toggle switch — shifts the overall character from a clear, glassy push to a more rounded, singing lead voice

Connectivity and Power

The pedal uses standard instrument-level connections on the front and rear of the chassis, making it a drop-in addition to any existing pedalboard signal chain. Power is supplied via an external 9V DC adapter rather than an internal battery, keeping the enclosure compact and stage-ready.

• Inputs: 1 x 6.3 mm jack (1/4") — accepts standard instrument-level signal from guitar or preceding pedals
• Outputs: 1 x 6.3 mm jack (1/4") — sends boosted signal to amplifier or next pedal in chain
• Power Source: 9V DC power supply — no internal battery compartment required
• MIDI Interface: No — designed as a straightforward, always-on or footswitch-controlled analog effect

Signal Character and Circuit Design

As a dedicated treble booster rather than a transparent clean boost, the Brighton is engineered to interact directly with the amplifier's input stage, adding harmonic richness and saturation that respond to playing dynamics. The analog circuit preserves the natural voice of the instrument and the amp, layering additional upper-midrange energy on top without compressing or coloring the fundamental tone.

• Circuit Type: Analog — discrete signal path that retains touch sensitivity and picking dynamics
• Pedal Type: Treble Booster / Boost — designed to push tube amps into natural overdrive rather than deliver clean volume lift alone
• Effects Loop: No — single in/out signal path keeps the signal chain simple
• Footswitches: 1 — single bypass footswitch for engaging or removing the boost from the signal path
