New Electronic Audio Experiments Longsword V4.6 Overdrive Guitar Effects Pedal
CONDITION:
From Electronic Audio Experiments:
The Electronic Audio Experiments Longsword is yet another contender in the endless void of op-amp based drive pedals—familiar but with some novel twists. 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.
Controls
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
