This 1983 Electro-Harmonix Small Clone Pedal is in Very Good vintage condition with moderate wear and tear for a pedal of this age.   

The Electro-Harmonix Small Stone is a classic analog phase shifter, first introduced in the 1970s and widely used in the 1980s, making original units from 1983 highly sought after by collectors and musicians alike.   

This pedal has the rare Reticon SAD1024 BBD (Bucket Brigade Delay) chip.  The chip consists of two independent 512-stage delay lines, which can be cascaded for longer delay times.  BBD chips like the SAD1024 work by passing the analog signal through a series of capacitors, creating a time delay that is essential for modulation effects.  The SAD1024 is prized for its wide delay range, extended bandwidth, and the unique sonic character it imparts to effects.
