Source Audio True Spring Reverb
The Source Audio True Spring Reverb combines the charm of natural spring reverb with pulsing tremolo. Not just depending on off-the-shelf reverb effects, the True Spring Reverb has been meticulously crafted and loaded into high-powered 56-bit Sigma DSP. All thanks to the two-man engineering team consisting of Bob Chidlaw and Jesse Remignanti who put years of collective manpower into capturing every nuance of spring reverb and tremolo. As a result, the True Spring Reverb offers indisputable sound quality with magnificent tonal depth and precision.
The Spring Reverbs
The Source Audio True Spring Reverb uses a pair of input and output transducer to inject an instrument’s dry signal into an actual set of spring coils. Therefore capturing the very distinct vibrations as the sound bounces back and fourth within the springs. The same technology adopted by Leo Fender back in the 1960s.
Short Spring Reverb
Firstly, modeled after the unmistakable blackface amplifiers of the 1960s; the Short Spring Reverb engine offers a taut sound with a quick decay and smooth trails.
Long Spring Reverb
Producing long and deep reverb decays with noticeable “drip” and highly animated trails. The LONG Spring engine is not as dramatic as the TANK Reverb. However, it does offer an extremely authentic representation of lively reverbs found in vintage combo amps.
Tank Spring Reverb
Finally, the Tank Spring Reverb captures the unmistakable effect of tube-driven spring tanks from the 60s. Replicating the sound of the classic Fender 6G15 and characterized by a “drippy” attack and animated trail.
Alternatively, the True Spring Reverb also allows you to combine any of its iconic spring reverbs with three tremolo effects. The True Spring Reverb’s tremolos are the same effects originally seen in the Vertigo Tremolo.
Firstly, Optical Tremolo is the effect found in so many combo amps of the 60’s. Relying on a neon light bulb as well as a light-dependent resistor called an “optocoupler”. The non-symmetrical aspects of the light and the optocoupler give the tremolo a distinctive choppy character.
First appearing in the fender “brownface” amps, the Harmonic Tremolo gives you a complex and pleasing tremolo with characteristics reminiscent of a phaser.
Finally, the Bias approach involves an LFO modulating the bias voltage of the tubes in an amp. Essentially, pushing the tubes in and out of saturation and resulting in a smooth amplitude modulation with a mild overdrive.
Above all, the True Spring Reverb gives you a truly versatile and feature-packed reverb pedal.
