Mayfly Introduces the Flat Earth Compressor

Mayfly Introduces the Flat Earth Compressor

The Flat Earth has minimal knob count and feed-forward compression circuitry.

The Mayfly Flat Earth uses Feed-Forward circuitry which determines the amount of compression by analyzing the signal before it’s compressed. Old school compressors (you know: the Red one, the Orange one, the Grey one)use Feed-Back circuitry which looks at the signal after it’s already compressed. This results in noise, pumping, and tone-loss.

Boutique pedals based on older designs try to get around these problems by adding more knobs: blend knobs, tone knobs, etc. According to Mayfly Audio, "The Flat Earth has minimal knob count to allow guitarists to get to ‘wow’ quicker."

  • Feed-forward compression circuitry: great compression that’s easy to setup
  • No pumping or other compression artifacts
  • Very low noise floor, very low distortion
  • Level, sustain, and attack controls. That’s all you need
  • Full bypass using relays with Fail Safe (automatically switches to bypass if the pedal loses power)
  • Cast aluminum enclosure with stunning artwork
  • MSRP $149 USD ($199 CAD) direct online

The session ace’s signature model offers a wide range of tones at the flip of a switch … or five.

Hello and welcome back to Mod Garage. Not long ago, I came home late from a band rehearsal, still overly excited about the new songs we played. I got myself a coffee (I know, it's a crazy procedure to calm down) and turned on the TV. I ended up with an old Bonanza episode from the ’60s, the mother of all Western TV series. Hearing the theme after a long time instantly reminded me of the great Al Caiola, who is the prolific session guitarist who plays on the song. With him in mind, I looked up the ’60s Epiphone “Al Caiola” model and decided I want to talk about the Epiphone/Gibson Tone Expressor system that was used in this guitar.

Slinky playability, snappy sounds, and elegant, comfortable proportions distinguish an affordable 0-bodied flattop.

Satisfying, slinky playability. Nice string-to-string balance. Beautiful, comfortable proportions.

Cocobolo-patterned HPL back looks plasticky.

Embracing the idea of an acoustic flattop made with anything other than wood can, understandably, be tricky stuff. There’s a lot of precedent for excellent-sounding acoustics built with alternative materials, though. Carbon-fiber flattops can sound amazing and I’ve been hooked by the sound and playability of Ovation and Adamas instruments many times.
