Canadian pedal maker Mile End Effects has launched a new pedal coquettishly named mthrfckr=rptr. It’s a preamp combined with a lo-fi delay, with a post rock-ish flavour; pre-orders are due to open soon.

Seemingly named after the Godspeed You! Black Emperor song motherfucker=redeemer, this new pedal from Mile End Effects is based on old analogue tape delay effects units. In the words of the pedal’s designers:

“The mthrfckr=rptr evokes something that can’t help but make you feel as though suddenly you have caught a rare glimpse into the very intimate lives of complete strangers from the past. As if you have unearthed a box of family photographs or film reels labelled ‘Summer Vacation 1962’ in the back of an estate sale.”

This effect is a combination of a tape machine preamp and a modulated, lo-fi tape delay, with controls for Vol, LFO Depth, LFO SPD, D.LVL, Gain, Time and RPTS. Three switches are labelled Wet, Wave and +dB, while two footswitches are available to engage the effect and a momentary latch respectively. The pedal uses the LFOs to emulate worn out old tape warble and the crankiness we all associate with these older mechanical tape-based delays. It then adds in additional colouring in the form of an old school tape preamp to get even closer to that retro sound.

Warp It!

An interesting feature is the wave control, that lets you choose either square or sine waves to emulate various tape speed anomalies, from sea sickness-inducing timing movement to full-on knackered old magnetic tape trying hard to keep up.


The non-cyclical LFO modulation control adds randomness to mimic the inconsistent modulation of physical tape being dragged across magnetic tape heads powered by a DC motor. The +dB is the cassette tape pre-amp switch and that momentary switch will get the delay repeats to warp and even self oscillate. If all this sounds like your kind of thing, then you need to check this thing out.
