Boss Compression Sustainer CS-3 Compressor Pedal - Blue - 2010s

The Boss Compression Sustainer CS-3 is a great addition to any pedal board. The CS-3 attenuates loud signals, while boosting quiet signals - adding sustain and bringing out the natural harmonics of the instrument. 4 controls for volume, tone, attack and sustain allow you to dial in a style of compression that suits you, and helps bring the best out in your playing. 

This pedal from the late 2010s is in excellent condition. Boss pedals are well known for their durability and near indestructible design.
