Compressors are very common these days, and there are lots of varieties of them out there. We opted for a simple but elegant version of an optocoupler based compressor to lead our lineup of pedals. Using a ‘Light Dependant Resistor’ hooked up to an LED that is driven by the input of your guitar, this pedal gently applies a shallow compression ratio to your guitar signal. This balances some of the dynamics found in your playing, bringing a smoother overall level to your signal by boosting low dynamic valleys and taming high dynamic peaks.
The Opto Compressor’s controls are fairly simple.
- The Sustain knob affects the amount of compression applied to your signal.
- The Level knob affects the overall output of the compressed signal that is sent to the output.
- The gain trimpot located internally gives you the ability to add a bit of ‘grit’ to your signal post compression and pre output level.
At high compression you will retain a lot of clarity to your signal, without giving your signal a ‘coloured’ texture that is found in other types of compressors. Opto-coupler based compressors are often appealing for their overall ‘transparent’ nature.
