Product Description

Turn on to the vintage charm of natural spring reverb coupled with pulsing tremolo. Source Audio doesn’t depend on the off-the-shelf reverb effects processors found in many modern reverb pedals, we handcraft every one of our proprietary effects engines and load them to high-powered, 56-bit Sigma DSP.  Our two man engineering team of Bob Chidlaw and Jesse Remignanti put years of collective man-hours into capturing every nuance and idiosyncrasy of the spring reverb and tremolo effects from some of the music gear industry’s most iconic guitar amps and outboard gear. The result is indisputable sound quality with magnificent tonal depth and precision.

The Spring Reverbs

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.

I'm not much of a pedals guy but I've bought some vintage 40's / 50's amps recently - and none had reverb. This pedal gives a really wide range of authetic reverb sounds.

Best spring reverb emulation I've heard. 3 distinct sounds from the toggle but really interesting when you get into the editor, plus the ability to add modulation, adjust pre-delay etc. The tremolo is excellent making this pedal fantastic value.

Mr alex howells24th Apr 2019

I saw the Premier Guitar review of this product with John Bolinger and was really impressed with the quality of the sounds available, I love the addition of the tremolo. The pedal is really easy to use with clear controls. The only thing letting it down is that you have to buy an additional remote tap control to operate the Tremolo or fiddle with a tiny button on the back. they should have just put a second switch on the top. I am really pleased with this pedal it has a wealth of superb spring reverb sounds and a lush tremolo which does not rob volume as some do. I'm really glad i bought it, its definitely a keeper.

Actualy the best sprint reverb in a box. Make a blind test with a real one and you'll see ...
