The phrase identifies a specific type of effects unit, specifically a reverb pedal manufactured by Strymon, that is being offered for sale as a used item. Such a purchase contrasts with acquiring the unit new from an authorized retailer. The condition of the unit can vary significantly, influencing its price and functionality.
Acquiring pre-owned musical equipment often presents a cost-effective alternative to buying new. In the case of high-end effects pedals, such as this one, the potential savings can be substantial. Furthermore, the availability of these units on the secondary market provides access to products that may be discontinued or difficult to find new. Historically, musicians have sought out used equipment for its unique characteristics or affordability, contributing to a vibrant market for pre-owned gear.
