RDRPT is an experimental device inspired by noise music, specifically no-input mixing techniques. It's intense, chaotic and loud. Feedback patching opens up a whole other world of possibilities for using effects you already own. A world that is as exciting as it is unforgiving.

Standalone, with nothing plugged into SND & RTN jacks, RDRPT can act as a distortion pedal, an oscillator, or a mute switch.

When other pedals or pedal chains are hooked up to SND & RTN, and RDRPT is on, it feeds a portion of their output signal (RTN) back into themselves (SND). When the pedal is off, the IN signal is connected to SND, RET to OUT. That way it is still possible to use the pedals sitting in the feedback loop when the device is off.

Controls

  • feedback knob controls how much of the RTN signal is fed back to SND;
  • gain knob controls how much of the IN signal gets to SND;
  • volume knob controls the overall output volume of the pedal, the OUT signal;
  • clip toggle puts clipping diodes in and out of the circuit:
    • o position puts clipping diodes just before the output of the pedal;
    • x position takes the diodes out;
    • f position puts the diodes into the feedback path;
  • phase toggle flips the phase of RTN signal before it is mixed with the IN signal;
  • RPT footswitch is a latching switch that turns the feedback path on or off;
  • FLIP footswitch is a momentary switch that reverses the RPT state. So if RPT is “off”, stepping on FLIP will momentarily turn the feedback on, if the RPT is “on”, FLIP will momentarily turn it off.

Caution

Anything feedback-related can lead to extreme changes in volume. Please be careful. As a precaution, it might be a good idea to place a limiter (or a distortion pedal on low gain setting) right after RDRPT to tame the sudden loud sounds.

When you have time-based effects in the loop like delays and reverbs, be careful with rolling off the volume knob. I’d recommend keeping it above 50% in this case. Experiment turning the loop on & off to find the optimal position. The issue here is that the volume knob and the clip toggle only take effect when RDRPT is on. That means there might be loud feedback going on that is tamed by RDRPT, and once you switch RDRPT off, all the reduction in loudness is off too. Then whatever delay / reverb tails are still pending might be unexpectedly loud.

Patch Ideas

Delay alterations

  • Put a Delay or a Reverb pedal into the SND/RTN loop. Set the Delay/Reverb pedal to minimum Repeats/Feedback/Decay, mix to 100%;
  • RDRPT’s feedback knob now becomes an external Repeats/Feedback/Decay control for the chain, basically replicating a function that normally exists inside the Delay/Reverb pedals and giving us access to it;
  • Try placing other pedals in series with the Delay/Reverb in the loop. For example a pitch shifter will give us shimmer-like sounds, a filter will give us filter-delay, bit crusher will lead to degrading delay repeats.

Controllable feedback 

  • Put a Volume pedal into the SND/RTN loop. A filter with an expression control would also work. Add other pedals in series with it if you like;
  • Put the Volume pedal into heel position, RDRPT’s feedback knob to maximum;
  • It is now possible to control the intensity of feedback with a foot pedal.

Mute switch

  • Put RDRPT’s Volume knob, Gain knob, Feedback knob on minimum;
  • RDRPT will act as a momentary or latching mute switch.

Oscillator

  • Set Gain to zero or disconnect your instrument from the IN;
  • Leave RTN unconnected or turn off pedals in the loop;
  • Feedback becomes a pitch control, clipping affects the characteristics of the oscillation.

Fits like a glove, looks like a million!
Size: Small, Color: Purple
Bought this as a gift for him and very impressed. Looks like a million dollars, fit true to size, looks tailored not cheap. Fabric is quality, stitching is done well and the pants have a nice hidden elastic extender that helps if he goes up or down a few pounds. Very impressed!

It was the perfect suit for our big day!
Size: X-Small, Color: Purple, Size: X-Small, Color: Purple
Purple size xs. He's 5'9" 145-150lbs. Very impressed with this suit. The color and pattern is awesome. The fit was good. I would say this suit runs large. Usually he wears a Medium in everything but ordered an XS and it fit very well. The pants were long we had to get those hemmed. There was a few stray strings by the end of the night in areas of the suit. But overall good quality. And for a great price.

We were excited and I wanted to like it but...
Size: X-Small, Color: Black, Size: X-Small, Color: Black
We ordered this for Prom and it was supposed to be a size small, which was available for Prime ordering, but had to settle for xsmall. The pants, fortunately fit well and just need to be hemmed, the vest is great and the jacket is snug. My son has broad shoulders and I was hesitant to buy the xsmall, but it does fit just right. The only thing he would need to do is unbutton the jacket while he is dancing and maybe take it off while seated and eating dinner before prom. The material is surprisingly nice and has weight to it. I was relieved it isn't flimsy. The overall look on my son is smooth and we love the pattern and the material has shine to it. I was not happy that right out of the package, the button to the jacket could potentially fall off during because it doesn't look securely sewed in. The side of the right side of the jacket has thread already coming apart. And I found a little snag in a different location. I'm really not happy about that. I posted photos so you can see what I mean. We were excited about this suit, but it's going back. The company needs to do better with quality control.
