Thermion releases PowerTrem and PowerVibe modulation pedals

May 1, 2025 · 3 sources

Thermion has released the PowerTrem and PowerVibe pedals, described by Gearnews as modern takes on two vintage effects¹. The PowerTrem is a tremolo pedal with classic and harmonic modes, and the PowerVibe is an analog optical vibrato pedal for electric guitar and bass²¹.

The PowerTrem has Intensity, Speed and Level knobs plus a switch between Classic and Harmonic modes¹. Thermion says Normal mode offers a warm, traditional tremolo volume, while Harmonic mode alternately modulates the high and low frequencies, creating a more complex and organic effect³. An internal switch selects sine or square waves³¹. Thermion lists 100% analog circuitry, true bypass, a 9V center negative 2.1mm DC jack, 35mA current draw, an input impedance above 1MΩ and an output impedance below 1kΩ³. The maker gives dimensions of 7x11x5cm and a weight of 235g, and says the pedal is built in Spain³.

The PowerVibe is an analog optical vibrato pedal inspired by classic rotating speaker and photocell-based modulation circuits, focusing on smooth pitch modulation rather than amplitude tremolo, according to PedalPedia². Gearnews reports that it recreates the classic Uni-Vibe effect, with Chorus and Vibe modes selected by a switch and Speed, Depth and Level knobs¹. It is also fully analog and true bypass, with an internal sine or square wave selector, and runs on 9V DC center negative at 50mA²¹. Gearnews describes Chorus mode as providing a fluid, spatial effect and Vibe mode as offering a darker, more expressive tone¹.

No US list price is given in the available material. Gearnews called the internal waveform switch awkward, writing that users may need a screwdriver to change waveform options¹.
