The Dedalo FX Gorila Compressor GOR4 is a professional bass compressor pedal from the Argentine maker Dedalo FX. It is an analog design built around optical technology and a studio-grade opamp, and RockBoard's PedalPedia says it was designed to bring recording studio quality to the pedal format1. For a bass player, that means a compressor intended to even out dynamics and add the kind of controlled sustain usually associated with studio outboard gear, in a housing that fits on a pedalboard. It sits among the wider field of compressor pedals and bass-oriented effects covered in bass pedals.
What it does
The Gorila is a compressor: it reduces the volume of loud notes and lifts quieter ones, so a bass line sits at a more even level. RockBoard's PedalPedia describes the GOR4 as a professional bass compressor, and the optical approach it uses is a design associated with classic studio level control, where a light-sensitive element responds to the signal rather than a voltage-controlled circuit1. The maker pairs that optical stage with a studio-grade opamp, the amplification stage at the core of the circuit1.
Dedalo also makes other pedals for bass players, including the Dedalo B-saurio, the Dedalo Byte and the Dedalo EQ-F1.
The maker's English manual for the GOR4 is published as a PDF on the Dedalo FX website1.
