Neurotron is a clone by AionFX of the Lovetone Ring Stinger.
These things are absolutely nuts and only a handful of original units were ever made.
They sell for $1200 to over $3000 depending on condition.
This clone is very faithful to the original, with only a few changes to the switching and bypass system.
This pedal is much more than a ringmod, it's also an octave fuzz, doubler/repeater/dirt box/optical synth all rolled into one.
Klangs, bells, metallic fx, pseudo vocoder fx, dalek noises, sci-fi atmospherics, spooky warbling, trem arpeggios, tonal toggling, touch sensitive keying, pitch crossfiring, microtonal and atonal fx, evolving drones, digeridoo fx and not least the meanest graunchiest octave fuzz ever. (description lifted from found sound)
Tons of CV/Expression/Ext Osc options means that this will be a fantastic pedal for integration with your other gear.
Onboard LFO can modulate PWM or FM of the ringmod oscillator.
