Source Audio True Spring Reverb

Source Audio True Spring Reverb is a stereo reverb/tremolo pedal with a vintage charm of natural spring reverb coupled with pulsing tremolo. The pedal has a indisputable sound quality with magnificent tonal depth and precision.

The reverb effects are based on a mechanical design originated by the Hammond Organ Company in the late 1930s. This stark design uses a pair of input and output transducers to inject an instrument’s dry signal into an actual set of spring coils and capture the very distinct reverberations as the sound bounces back and forth within the springs. Of course, Leo Fender adopted this design in the 1960s with the some of his “blackface” amplifiers and a revolution was born.
​
Short Spring Reverb: Modeled after the unmistakable twang of “blackface” amplifiers of the 1960s. After extensive research we found tremendous diversity in the spring reverb sounds of a variety of amps. Some offered a tighter, less animated tone while others sounded “drippier,” with longer sustain and livelier reverb trails. The SHORT Spring reverb engine offers a taut sound with a quick decay and smooth trails.
Long Spring Reverb: Produces long and deep reverb decays with noticeable “drip” and highly animated trails. The LONG Spring engine is not as dramatic as the TANK Reverb engine, but does offer an extremely authentic representation of some of the livelier reverb tanks found in vintage combo amps.
Tank Spring Reverb: Captures the unmistakable effect of the tube driven outboard spring tanks of the 60s. The sound of reverb tanks like the classic Fender 6G15™ are characterized by their “drippy” attack and animated trail. This original two-spring design produces a bouncing, delay like sound inseparable from the early days of surf rock and spaghetti western soundtracks.

The True Spring Reverb also allows you to combine any of its iconic spring reverbs with any of the pedal’s three tremolo effects. The True Spring’s tremolos are the same organic effects that originally appeared in our Vertigo Tremolo – the winner of Guitar Player’s “Hall of Fame 2015” and Premier Guitar’s “Premier Gear Award.”

The pedal can be used with the Neuro Mobile App (available for free at the App Store (iOS) and Google Play (Android)). The Neuro Desktop Editor is available as a free download for Mac or Windows systems on our Downloads page. These powerful editing tools offer an advanced collection of deep editing parameters. After customizing your sound, burn it directly to the pedal and easily access it anytime without having to reconnect the Neuro Mobile App or Neuro Desktop Editor.
