Tremolo
Harmonic bias tremolo splitting signal into high and low bands that pulse out of phase. 1960s Fender-amp inspired.
Custom Tones, founded by Rob Hall, specializes in Dumble-inspired circuits. The Ethos 60's Harmonic Bias Trem captures vintage amp tremolo character.
The Ethos 60's Harmonic Bias Trem recreates the unique tremolo circuits found in 1960s amplifiers. The harmonic bias approach creates a more complex, textured tremolo than simple volume modulation.
With decades of engineering expertise behind the design, the Ethos Trem delivers authentic vintage amp tremolo in pedal form.
