Definitive Spring Reverb Tone and Three Sweet Tremolo Modes

This article was Written By

Get to know them!

The Source Audio True Spring Reverb pedal packs some of the most realistic spring reverb tones you'll find in a pedal. And if that isn't magical enough for you, it also boasts three vibrant tremolo effects. From short ambient bursts to splashy tank-style surf reverb, the True Spring Reverb pedal delivers definitive spring sound, and you can tweak the spring tone to an astonishing degree with the free Neuro Editor software. Once you've created your custom tones, you can save up to three presets on the pedal for instant recall. If you've thought that you'll never be able to get a true spring reverb sound out of an effects pedal, then you need to try the Source Audio True Spring Reverb.

Three spring modes

The True Spring Reverb pedal's three spring modes — Short, Long, and Tank — cover a lot of sonic territory. The Short setting "offers a taut sound with a quick decay and smooth trails," inspired by '60s Blackface amps. The Long mode "produces long and deep reverb decays with noticeable 'drip' and highly animated trails." Finally, Tank mode is based on the sound of classic tube-driven reverb units, "characterized by their 'drippy' attack and animated trail." We've heard a lot of spring reverb pedals here at Sweetwater, and the True Spring Reverb is one of the most accurate emulations we've ever experienced.

Three tremolo modes

By holding the Control Input button on the True Spring Reverb pedal, you gain access to controls for the tremolo effects. In this mode, the toggle switch selects between Opto Tremolo, Harmonic Tremolo, and Bias Tremolo. Opto mimics a photocell tremolo effect with its distinct choppy character. Harmonic mode is based on early-'60s Brownface amplifiers, alternately modulating bass and treble frequencies. And Bias mode delivers the smooth, overdriven sound of tube-saturated tremolo.

Customize your tone with the Neuro Editor

Right out of the box, the True Spring Reverb pedal delivers authentic spring reverb tone — the icing on the cake is Source Audio's Neuro Editor software. Available for your smartphone as well as your desktop computer, Neuro takes you inside the pedal's powerful 56-bit Sigma DSP and allows you to fine-tune all sorts of parameters, from number of springs and spring length to pre-delay, diffusion, and much more. Once you've created your ideal effects, you can save up to three of them on the True Spring Reverb pedal for instant recall, without ever having to open the editor again.
