Electronic Audio Experiments Longsword

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, semi-parametric 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 guitar, 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

• Clip - selects between diodes to alter dynamics and headroom, with the following settings:

• Boost (Footswitch) - engages a pre-gain boost circuit with a moderate mid boost

• Boost (Knob) - adds up to 20dB of gain when the Boost is engaged

This pedal comes in a powder-coated 1590BBM enclosure. 

Additional features include true bypass relay switching, a standard power supply (9VDC 2.1mm center negative), and top-mounted jacks. 

All Longswords come with the standard limited warranty.
