V4.6 (updated June 2026, serial #3253)

• • Added intelligent momentary/latching behavior to footswitches
  • Reduced switch pop when engaging Boost circuit
• The Electronic Audio Experiments Longsword is yet another contender in the endless void of op-amp based drive pedals, but it is one that takes the topology in a novel direction. Cascaded gain stages allow for the full range from clean boost to massive distortion, all without sacrificing tonal flexibility. The equalizer combines bass and treble shelving filters with an active, frequency-selectable midrange boost/cut control. This lets the user sculpt a diverse array of tones and carve out a niche in even the most dense of mixes. The Longsword has a broad frequency response which makes it work equally well with guitar, baritone, and bass.
  
  Level: output volume
  
  Drive: go from light grit to heavy overdrive
  
  Low/High: James/Baxandall tone stack (shelving filters)
  
  Mid: active midrange boost/cut
  
  Shift: selects frequency controlled by Mid pot
  
  Diode: selects between clipping diodes, to alter dynamics and headroom
  
  Up: MOSFET clipping, medium compression
  
  Center: no diodes, minimal compression
  
  Down: Silicon diode clipping, maximum compression
  
  Boost (Footswitch): engages a front end mid boost
  
  Boost (Knob): adds up to 20dB of gain when the Boost is engaged
  
  Bypass: Relay switching with true bypass
