Harmonic Tremolo
Harmonic tremolo recreates the unique circuit included in some 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
Bias tremolo is an approach to tremolo that 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.

Additional Spring Reverb Engines

In addition to the True Spring's primary reverb engines, the Neuro Mobile App and Neuro Desktop
Editor offer an extra collection of diverse reverb effects. These reverb effects provide a refreshing
variety of tonal options. Visit the
bonus reverb engines.
Drip Machine
This vibrant effect offers a cascading trail of tremendously drippy reverb reflections.
Tiny Tank
The super-tight Tiny Tank imagines the sound of a reverb tank half the size of traditional tank
dimensions. It produces a strong initial splash with a quick, metallic decay.
Space Spring
This especially prominent effect combines a quick Harmonic tremolo with an accompanying pitch
modulation in the reverb trail. It is quite dramatic, yet very musical.
Three Spring Tank
Unlike the classic two spring reverb tanks, which produce a highly animated sound with distinct
reverb reflections, three spring designs offer a rich reverb effect with a smooth decay. It is a perfect
sound for those looking for subtle spring characteristics with a beautiful, lush trail.
Hall S
This beautiful effect imagines the unlikely cross-pollination of down-and-dirty 60s spring reverb with
lush-and-lofty 80s Lexicon™ Hall reverb. It is a massive, lingering reverb with a smooth and subtle
modulation.
Trash Can Spring
This nasty reverb is exactly what you might expect. Imagine the sound of a spring tank reverberating
through an old metal trash can – it's trashy!
