This Pedal is currently available.
Octave up pedal
Functionally the same as a "Green Ringer" or "EQD Tentacle" type octave circuit when both knobs are set to max
Mix knob (left knob) to tame the harshness, brings back the fundamental, highly useful for retaining low end on bass!
Filter knob (right knob) sweepable low pass filter comes before the octave changing the response for an even more pronounced and singing octave, (the clean tone on your mix knob is not filtered)
Combines beautifully before or after any dirt pedal, seriously, the octave fuzz pedal you are looking for is simply just this pedal combined with whatever your current favorite dirt pedal is.
Works wonderfully on bass! You really have to hear this, it adds all the edge and growl you might want from a distortion pedal but doesn't add any extra compression
IMPORTANT I see YouTubers sometimes mention green ringer has "tracking issues" this is wrong. There is 0 latency there are no tracking errors, it makes skronky ring mod noises on chords and double stops. This is not a bug, it is a feature! this is the sound! Get your screaming leads and sonic youth noise jams
ABOUT THE FINISH There will only be 4 that look exactly like this! The company that used to do drilling and painting for me disbanded.
