The DOD FX80B Compressor Sustainer is an updated version of the original FX80 introduced in the mid 1980s. It features three controls: Level, Compression, and Release, allowing users to adjust output volume, compression strength, and release time. The pedal provides smooth and natural sustain while maintaining the original tone and dynamics of the instrument. It delivers subtle compression suitable for rhythm or clean lead tones. The FX80B is part of DOD’s classic analog series and was manufactured in the United States.
