Positive Grid Optical Comp is a compressor pedal and is available under the Comp effect group and is inspired by the BBE Opto Stomp.
The BBE Opto Stomp Optical Compressor Pedal is a stomp-box style pedal producing vintage soft-knee optical compression for guitars, bass and keyboards. The Opto Stomp’s compression and tone are reminiscent of the best vintage compressors made in the ’60s.
The Pad switch on the pedal attenuates input to accommodate active or passive instruments. It is recommended to use -15dB for active and 0dB for passive instruments.
