2023 production , in near mint condition with original box & instruction leaflet. In 100% perfect working order.
Also has Japanese supplied multi-input voltage powersupply. Works better on our in-house Vitoos 500ma output p/s IMO

A truly versatile Boost & Overdrive pedal that really does both things well. It all depends where you put the Drive Control .
Massive voltage pump that ups the internal voltage to 30 volts means the tube is not just there for decoration!
