Vintage Spring Reverb And Tremolo In One Pedal
The Source Audio One Series True Spring Reverb Pedal combines classic spring reverb tones with authentic tremolo effects in a single compact stompbox. Designed for guitarists who want the sound and feel of vintage tube amplifiers without hauling heavy gear, this pedal delivers studio-grade spring reverb and expressive tremolo that work equally well on stage, in the studio, or at home.

Authentic Spring Reverb Modeling
At the core of the True Spring is detailed DSP modeling based on original spring transducers and coil designs made famous in classic American amplifiers. The pedal offers multiple spring reverb voices that range from tight and controlled to deep and dripping, capturing everything from subtle ambience to bold, surf-style trails. Each reverb type reacts dynamically to playing style, preserving attack clarity while adding depth and character.

Classic Tremolo Effects With Musical Response
Alongside its reverb engines, the True Spring includes three distinct tremolo styles inspired by vintage amplifier circuits. These tremolos provide smooth pulses, choppy modulation, or complex harmonic movement depending on the selected mode. Reverb and tremolo can be combined freely, allowing players to layer lush space with rhythmic motion for expressive, period-correct tones.

Hands On Control With Flexible Operation Modes
The pedal features an intuitive control layout with dual-function knobs that adjust both reverb and tremolo parameters. A toggle switch allows quick access to different effect types, while standard and preset operation modes let users choose between traditional stompbox behavior or saved settings for fast recall. This flexibility makes the pedal suitable for both minimalist rigs and preset-based setups.

Stereo Routing And External Control Options
With stereo inputs and outputs, the True Spring integrates seamlessly into mono or stereo rigs. Multiple routing options support everything from simple signal chains to advanced wet/dry or loop configurations. External control is available via expression pedals or compatible motion controllers, and tap tempo support allows precise tremolo timing during live performance.

Expanded Editing And MIDI Integration
For deeper customization, additional parameters can be accessed through the Neuro mobile app, enabling fine control over effect behavior beyond the front panel. When paired with a compatible hub, the pedal supports full MIDI control for preset management and automation. This makes the True Spring a powerful option for modern pedalboards that require both classic tone and advanced control.
