This pedal is in excel condition,hardley used. Because it is a completely passive device (meaning it requires no power supply, batteries, or complex digital components), there is very little that can actually break or wear down over time. As long as the jacks and the single volume pot are clean and scratch-free, a used one will function identically to a brand-new one.
Quick Reminder on Placement:
Since it acts as an external master volume to let you crank your preamp tubes at bedroom levels, just remember that it must be placed directly into your amplifier's series effects loop (connecting the amp's FX Send to the pedal input, and the pedal output to the amp's FX Return). Running it straight into the front input of an amp will just act like a standard guitar volume pot and cleanup your overdrive signal rather than taming the overall volume.
