Description: 

The True Spring’s 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 (Outboard Spring): 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 Tremolos

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.

      Features:

  • 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.
  • Includes 9v DC power supply (300mA / Negative Tip)
  • Includes 1/8” to 1/4” cable for Neuro Mobile App connection.
  • Power Consumption — 165mA
  • USB port — Connects to Mac or Windows PC for firmware updates and the forthcoming in-depth effects editing software.
  • Brushed anodized aluminum housing.
  • Dimensions: L: 4.5 in./11.4cm x W: 2.75 in./7cm x H: 2 in./5.1cm (including knobs)

    Amazing chair
    Color: Black
    Going from a regular office chair to this majestic heavenly office chair, my body hasn't felt better. As a person who is rather on the large side (6'2, 175 pounds), so this chair good butt cushioning, adjustable armrest, the adjustable headrest made this purchase an very good one. I move constantly on chairs so when i found out tthis chair can adapt to my position with a few tweaks i instantly fell in love. Considering that I have jumped and stood on the chair quite the number of times and it still is holding its form just speaks to its sturdiness. I dont believe in buying extremely expensive chairs as a high quality one like this has everything you could wish for.

    Wow Great Deal!
    Color: Black
    I have been using this chair for a month now and I am honestly impressed for the price I paid. I work from home so am using this chair 24/7. I had no issues with assembling it myself as a 35 year old female. Instructions were simple to follow and took me maybe 30 minutes to put together. Its sturdy and comfortable. I appreciate the padded arms and the seat bottom is also a nice thick cushion. Added bonus for the head rest and that it is adjustable. Definitely recommend.

    Good quality and arrived quickly
    Color: Black
    I was very pleased with how easy this chair was to set up. Affordable, arrived quickly. The only reason it isn’t 5/5 is because on of the arms had a small dent, possibly due to not enough bubble wrap during shipping. Other than that, the quality is great.

    Awesome chair so far
    Color: Black
    My old chair can go in the trash immediately because it set the bar so low (picked up from a giveaway - squeaked anytime it's leaned on, always sinking upon sitting on it). This Ergonomic chair blew it out of the water. Happy with this purchase. This chair took me an hour to assemble, which I expected. It feels extremely sturdy and comfortable. Lumbar support feels great! I love the various adjustability options this chair offers. Hope it lasts for many years. By the way, I am 175 lbs, 5'10".
