Wren and Cuff Eye See 78

Talking shop about Muff-style fuzz with any guitar player that knows his or her stuff is a relatively straightforward conversation. This is what lead to the birth of the Wren and Cuff Eye See 78.

Aside from the myriad of variants, the talk usually evolves into transistors and who used which variant.

There was a curious time in Muff history, when the circuit designed changed drastically.

In 1978,  operational amplifiers replaced transistor.

This particular variant was only manufactured for around two years. As such, only a few thousand ever made it out of NYC alive.

Fast forward to 2014

The Muff masters at Wren and Cuff have crafted the definitive version of the non-transistorized fuzzbox. They call it the Eye See Pi.

Apart from the lack of transistors, the Eye See Pi features a drastically different clipping section. This is brcause it gave a monstrously woolly sound, such as Smashing Pumpkins Siamese Dream.

As expected, the sound of the Eye See Pi is different from a standard Muff circuit.

While most vintage muffs are a little “sweeter” sounding, the Eye See Pi is certainly crunchier and more ballsy than a standard Muff.

In 1978, a switch was added to the back of the original, and the Eye See Pi includes this switch as well.

The control is labeled as “Tone Bypass” on both old and new pedals.

Essentially, it removes the passive tone stack from the circuit for a volume boost and a significantly more raw and open sound.

Of course, this switch renders the tone control useless, but we’re guessing that in this mode, you won’t miss it—this switch is just too cool.

If you’re looking for a largely-untamed IC-based fuzz and distortion machine, with the ability to adapt to most genres of music under the sun, look no further than the Eye See Pi. Here it is.

Wren and Cuff Eye See 78 Pi Features:

  • Authentic recreation of the 1978 IC Big Muff from the masters of the circuit, Wren and Cuff

  • Tone Bypass switch for a different flavor of Muff

  • Smaller Footprint than the original

  • True bypass switching

  • Standard 9v center-negative operation
