Longsword

The Longsword by Electronic Audio Experiments is an op-amp based drive pedal featuring cascaded gain stages that allow for a wide range of tones from clean boost to massive distortion. The pedal offers the following features and specifications:

- Controls:
- Level: output volume
- Drive: 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

- Electrical Specifications:
- Bypass: Relay switching with true bypass
- Input impedance @ 1 kHz: 500kΩ
- Output impedance @ 1 kHz: 1kΩ
- Power: 9V DC, 2.1 mm center negative barrel. The current draw is 75 mA. It is recommended to use a regulated, isolated power supply rated for 100 mA minimum. The PSU input is protected against reverse polarity and over-voltage up to 24V. The pedal does not accept batteries.

The Longsword is designed to work equally well with guitar, baritone, and bass, offering a broad frequency response. It comes in a powder-coated 1590BBM enclosure and features true bypass switching.

The pedal has undergone several updates, with the current version (V4.5) featuring a new mechanical format, power supply over-voltage shutdown circuit, and increased Low/High control crossover frequency.
