Out of the box, the True Spring Reverb couldn’t be simpler – just plug it in, select from the three onboard reverb engines, dial in some tremolo if you like, and start making beautiful music. But something deep and powerful resides just below the surface - the truly “Big Idea” behind all of our One Series pedals is the second, far deeper, set of options and editing tools for crafting the perfect tone. The Neuro Mobile App is 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.
- Three Distinct Spring Reverb and Tremolo Effects.
- Two Modes of Operation – Use the pedal in Standard Mode for a classic (non-preset) stompbox experience or turn on Preset Mode and save a user preset (including reverb/tremolo effects and knob positions) to each of the three toggle switch positions.
- Flexible Stereo Routing – The True Spring is equally at home in a mono or stereo rig. The pedal’s stereo inputs and outputs offer a variety of routing options such as Stereo to Stereo, Mono to Mono, Mono-to-Stereo, Stereo Sum-to-Mono and External Loop Mode.
- Universal Bypass — Select Active Analog (Buffered) or True Bypass.
- Secondary Tremolo Controls - Press and hold the CONTROL INPUT button to access the True Spring's tremolo effects (DWELL knob controls tremolo DEPTH / TONE knob controls tremolo RATE / toggle switch selects tremolo type).
- Expression Control — Compatible with Source Audio expression pedals and the Hot Hand 3 Universal Wireless Effects Controller. Assign up to three simultaneous parameters with editable depth and direction.
- External Tap Tempo – Use the Source Audio Tap Switch to tap in the tremolo rate with a choice of four different beat divisions (quarter, eighth, triplet, and sixteenth).
- External Tremolo Engage and Bypass – Use the Source Audio Tap Switch to engage or disengage the tremolo effects on top of an active spring reverb.
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.”
- Opto Tremolo: Optical tremolo (a.k.a. “Photocell Tremolo”) is the effect found in many combo amps of the 1960s. This version of tremolo relies upon a neon light bulb and a light dependent resistor called an "optocoupler." The non-symmetrical aspects of the light and the optocoupler give the tremolo a distinct choppy character.
- Harmonic Tremolo: This unique effect first appeared in Fender™ “brownface” amps made between 1959 and 1963, which alternately modulated the levels of bass and treble frequencies in the audio signal. The result is a very pleasing and complex tremolo that has characteristics reminiscent of a phaser.
- Bias Tremolo: This approach to tremolo involves using an LFO to modulate the bias voltage of the tubes in an amplifier. This essentially pushes the tubes in and out of saturation. The result is a smooth amplitude modulation with a mild overdrive created by the tube saturation.
