Pair authentic spring reverbs with organic tremolo effects.
The True Spring Reverb incorporates 3 Spring Reverb sounds from the Source Audio Ventris with 3 Tremolo styles from the Vertigo Tremolo.
On the reverb side, the True Spring lets you choose between the reverb tones of vintage combo amps or the "drippy" sound of tube-driven outboard units.
Each reverb works in tandem with any of the pedal's three tremolo effects (Opto, Bias, and Harmonic).
The True Spring Reverb also offers a full-suite of modern effects pedal features.
Highlights include stereo Inputs and Outputs, full MIDI control, true or buffered bypass, bypass trails, and external expression control.
The Spring Reverbs:
• Short Reverb: Modeled after the unmistakable twang of 1960s Blackface amplifiers. A tight sound with a quick decay and smooth trails.
• Long Reverb: Representative of the livelier tanks found in some vintage amps. Long and deep reverb decays with noticeable “drip” and highly animated trails.
• Tank Reverb: Inspired by tube-driven outboard spring tanks of the 1960s. A bouncing, delay like sound. Think surf rock or spaghetti western soundtracks.
The Tremolos:
• Optical tremolo: The effect found in many combo amps of the 1960s. This tremolo has a distinct choppy character.
• Harmonic Tremolo: First appeared in Fender Brownface amps. A pleasing and complex tremolo that has characteristics reminiscent of a phaser.
• Bias Tremolo: Essentially pushes the tubes in and out of saturation. A smooth amplitude modulation with a mild overdrive created by the tube saturation.
Neuro Editing System:
The True Spring features a large set of editing parameters when connected to the free Neuro Desktop Editor or Mobile App.
Access alternate virtual spring lengths, extended EQ possibilities, advanced signal routing, reverb pre-delay, reverb modulation and more.
The App also lets you place the tremolo effect before or after the reverb tank.
After creating highly customized presets with the Neuro Editor, users can easily organize, save, and share them with other musicians in the Neuro Community.
