Radikal Technologies - RT-1701 EFFEXX


High-class effect processor and more – The RT-1701 Effexx is composed of a stereo gain stage with overdrive, an equalizer respectively filter section, two multi effects and a reverb. Thanks to the module’s routing options, users can link components in various ways. The multi effects offer two types of echo, chorus, phaser and flanger as well as rotary, pitch shifter and Karplus Strong algorithms. For editing programs, there are several potentiometers and buttons. Configurations can be saved as so-called snapshots. A morph function makes it possible to crossfade smoothly from one memory slot to another via an internal LFO or an external CV signal. While doing this, the module interpolates between the parameter settings of both data sets.

In use, the RT-1701 shines with high-resolution sound. Its delay algorithms can be utilized to create atmospheric echo effects as well as tonal sound colorations. Chorus, phaser and flanger have a very lively character. The reverb processor delivers room simulations in studio quality. The Karplus Strong algorithm is controllable via 1V / octave. Therefore, users can play the results like an oscillator.


The RT-1701 Effexx comes equipped with the following stereo stages:

  • Input section with overdrive circuit
  • Equalizer respectively filter section with eight modes of operation
  • Two multi effects, each featuring eight algorithms:
    • Delay
    • Tempo Delay
    • Chorus
    • Phaser
    • Flanger
    • Rotor
    • Pitch Shifter
    • String Filter (Karplus-Strong)
  • Reverb
