Wampler Tumnus Overdrive Pedal with Treble Control

The Wampler Tumnus Overdrive is a highly regarded transparent-style overdrive inspired by one of the most iconic low-gain boost circuits ever made. Known for its ability to enhance your natural amp tone rather than overpower it, the Tumnus delivers exceptional clarity, harmonic richness, and dynamic response in a compact pedalboard-friendly format.

This version with added Treble Control expands the original circuit’s tonal flexibility, allowing players to fine-tune high-frequency response for different guitars, pickups, and amplifiers. From subtle clean boost to edge-of-breakup warmth and smooth, singing lead tones, the Tumnus excels at adding presence, definition, and just the right amount of drive without sacrificing articulation.

Its highly responsive design reacts beautifully to picking dynamics and guitar volume adjustments, making it a favourite for players who want their overdrive to feel like a natural extension of their amplifier.
