Super nice Roger Mayer Concorde + Treble Booster with box and sticker.

This pedal was fully tested and works as it should with no issues.

The Roger Mayer Concorde+ Treble Booster is a hybrid silicon and germanium guitar effects pedal based on a 1961 design originally built for Jimmy Page.

Key Specifications & Features

• Circuit Design: Combines a low-noise Class A silicon first-stage drive circuit with germanium components and passive tone shaping.
• Controls:
• • Drive: Adjusts first-stage silicon gain and harmonic distortion.
  • Tone: Operates as an inter-stage passive EQ.
  • Output: Controls the final level and amp overdrive amount.
• Enclosure & Design: Housed in the modern Vision Series chassis with side-mounted, pedalboard-friendly jacks.
• Bypass & Outputs: Features multi-mode capabilities including a hard-wire bypass and dual buffered outputs.
• Power & Battery: Runs on an external 9V DC power supply (negative center pin, 50mA+) or an internal battery boasting over 150 hours of life accessed via a tool-less sliding panel.
• Dimensions & Weight: Measures 170 × 112 × 57 mm and weighs 618 g.

Tone & Performance

• Dynamic Response: The drive reacts directly to your picking dynamics—playing softly cleans up the tone, while digging in adds punch and clarity.
• Gain Range: Functions as a clean-to-dirty boost at lower settings and transitions into a saturated, fuzz-like character at higher gain levels.
