Described by Soundtoys as "the ultimate realization" of their absolute obsession with delay effects, this plugin captures decades of echo and delay sounds in one versatile effect, offering 30 built-in styles carefully modelled on vintage classics such as the Roland Space Echo, Maestro Echoplex and Electro-Harmonix Memory Man. If you buy one delay plugin this Cyber Monday, make it this one.

Soundtoys Little AlterBoy: was $100, now $50.34
A fun, easy-to-use vocal processor, Little AlterBoy is a little plugin capable of producing a huge range of different vocal transformations. Shift your vocals pitch up or down by an octave or dramatically alter the tone by using the formant-shifter, while dialling in tube-modelled saturation using the Drive knob. And if you're after the hard-tuned robotic sound that's all over the charts right now, Little AlterBoy can do that too.

Soundtoys FilterFreak: was $151, now $31
Faithfully reproducing the sound of classic analogue resonant filters, FilterFreak is one of the most musical filter plugins we've ever tested.

Soundtoys Crystallizer: was $151, now $31
Cast your mind back to '80s hits and you'll inevitably recall the sound of the Eventide H3000, a famous rackmount effects processor. Crystallizer captures the unmistakeable vibe of that unit's Crystal Echoes preset, a unique combination of pitch-shifting and reversed echo that transforms any signal into shimmering futuristic textures. Soundtoys have brought this classic effect into the 21st century with a number of smart additions, including MIDI sync, a built-in gate and onboard low and high-pass filters.
