The Fairfield 20% More is unlike anything else on the market. It's not your typical distortion – the slew limiting creates a really unique, almost synth-like character. This is perfect for experimental guitarists, synth players, or bassists wanting to add a really distinct, warm edge to their sound.

Product Description

Fairfield Circuitry 20% More Slew Limit Distortion, Effect Pedal for Electric Guitar or Electric Bass

  • Versatile slew limiting distortion pedal for guitar
  • bass
  • synthesiser and virtually any other imaginable audio source. It uses a slew limiter to control how quickly the input voltage changes and limits it to a fixed volts-per-second rate. As time and frequency are inextricably linked
  • this process produces a steep
  • slightly distorted low-pass filter. When the pedal goes into resonance
  • the fixed waveforms transform into triangle waves
  • which form the backbone of the unmistakable sound of ‘20% More’. Furthermore
  • if the input signal is strong enough
  • it can overdrive these oscillations
  • resulting in pseudo-wavefolding and unique synthetic distortion artefacts.
  • Controls: Input
  • Blend
  • Volume
  • Slew
  • Feed
  • LPG (Low Pass Filter)
  • Switches: E = Envelope Destination (LPG or Feed)
  • U = Octave Up (0 or 1 octave)
  • D = Octave Down (0
  • 1 or 2 octaves)
  • LED: Effect on
  • Footswitch: Effect bypass
  • Input and output: 6.3 mm jack
  • S: 3.5 mm Stereo jack
  • CV over Slew Limiter Frequency
  • CV/Exp: 6.3 mm stereo jack
  • Power supply connection: barrel connector 5.5 x 2.1 mm
  • centre negative
  • Current consumption: 20 mA
  • Power supply with a 9 - 9.6 V DC mains adapter (not included in the scope of delivery

Frequently Asked Questions

The Blend control isn't just mixing distorted and clean signals; it's blending the original input with the slew-limited output, retaining more of the original signal’s dynamics.
While it excels at warmth, pushing the resonance and input can create some surprisingly aggressive textures, but it’s not a high-gain shred machine – it’s more about unique character than raw saturation.
Start with low resonance settings and gradually increase it while carefully monitoring for unwanted oscillation or hum; a good power supply is essential to tame potential noise.
