OOPEGG Super Retro Compressor / OCP-1 There is some wear and tear, but there are no issues with its operation. This is a highly practical, full-analog circuit compressor pedal developed to meet the needs of guitar compressors in recent live performances and recordings, and to be usable in various genres of performance environments. It is designed with practicality and flexibility in mind, allowing for strong compression to make your guitar sound stand out in various situations such as cutting and lead solos. The main features of this product include the ability to create a variety of sounds by adjusting the TONE knob, cutting unnecessary low frequencies during cutting, and cutting high frequencies during lead solos to create a thick and sustained sound. Furthermore, turning the VOLUME knob to the right (clockwise) allows for use as a clean booster to increase the volume during guitar solos, and also supports volume level correction.
