BOSS CS-3 Compression Sustainer

Selling my CS-3 Compression Sustainer which comes with its original box and original manual.
The item has been used (rarely) but has been well looked after and is in full working order.
The CS-3 replaced the CS-2 in 1986 and has since then been the only Boss pedal compressor available. This pedal will compress high input signals and boost low input signals to produce sustain. Boosting low-input signal means that noise will be boosted at the same time so it is easy to compress the signal too much and end up with a very noisy signal.
