Overview

The bx_opto Pedal is a slimmed-down version of the bx_opto. It provides a great way to get that charismatic compression of the bx_opto with a simpler interface, lower price tag, and guitar pedal feel. After meticulously modeling the light-dependent circuits of several optical compressors, the bx_opto has amalgamated into a beastly little dynamics processor, teeming with character and spitting out sounds like no analog optical compressor can do. 


In addition to providing tone-laden compression, the bx_opto Pedal doubles as a gain pedal. By dialing-in the Density and Level Trim controls, you can add that little extra taste of gain and color that’s needed.

Most optical compressors are appreciated for their musical, program dependent character produced by the light dependent circuitry of the sidechain. They allow users the ability to adjust the effect of this character by introducing a separate resistance circuit that gives some control over the compression envelope.

Brainworx decided to take a different approach to adjusting this compression envelope when modeling the bx_opto and bx_opto Pedal. The modeled physical constant of the Light Dependent Resistor (LDR) was influenced by those of very real compressors, but there is no separate envelope circuit. Rather, the constant is directly manipulated by the ‘Speed’ parameter of the plugin. This introduces a whole different approach to sonic character that is impossible to replicate with a ‘real-world’ optical compressor.

Features

  • The same optical compression circuit as the bx_opto
  • All in one sidechain input/makeup gain, ‘Density’
  • ‘Speed’ knob controls the modeled physical constant of Light Dependent Resistor, creating unique transient response
  • Output trim prevents overdriven signal from clipping
  • Guitar-pedal style power button

    I like using this like it's just another pedal for my guitar and bass. I've heard people say compassion isn't needed for electric guitar, but I disagree. I think this little stomp box sounds great.

    Great little plugin to bring a DI guitar or bass track to life. Colors in a very unassuming way, and really helps add punch without saturation or distortion.
